[Q] HDMI output, audio poor quality? SOLVED, see #32 - Xoom Q&A, Help & Troubleshooting

Hi
I just got a UK Wi-Fi Xoom, and started out by installing 3.1 and tiamat 1.4 OC kernel on it.
Now i hooked it up to my amp/tv (Onkyo amp, Panasonic TV) but no matter what i played, the audio quality was really poor (no bass, sounded like 8khz mono). Actually the audio coming from the built in speakers sound better! The cable should be fine, as i briefly tried it with an Optimus 2X, and as far as i remember audio was fine...
Any ideas?
Edit: Solved! See #32

This might not be the best test but I hooked up my Xoom directly to the TV which outputs to a pair of Bose bookshelf speakers and Angry Birds sounded great.
What I found off was the color quality of the home screen and through Quick Pic and stock Gallery. Angry Birds looked and played fantastic. My 3 and 5 year olds were glued to the screen. To fix the color I probably need to play with the color settings on the TV...no biggie. Haven't tried a movie yet.

Hi
After i wrote this i tried connecting it directly to the TV. Same result... (crappy audio). I only tried movies/music, and not games, which really dosent matter that much

same problem for me, European 3G Xoom running 3.0.1
Image quality is good, audio very poor.

I have also noticed that the audio quality leaves alot to be desired when using the HDMI out. Granted I am playing them through my TV speakers, but it does seem to be of lesser quality then other sources like OTA TV. Colors also seem a bit off, or over saturated or something. Maybe playing with the TV color settings would help that.
But its still pretty cool that xoom has HDMI mirroring, I use it alot.

I have the same problem... Connecting the audio via the 3.5mm jack sounds great, but connecting via HDMI seems to only send 2 channel audio, with no bass, maybe even at a lower bit rate (not sure, but it sure sounds crappy).

Same issue here. The audio is also heavily clipped. I tried to adjust the volume on the XOOM to at least alleviate the clipping, but I found that the volume controls have no effect on the HDMI out volume (at least on Android 3.1 + Tiamat 1.5 GHz with GPU OC).

I can confirm that the volume controls also has no effect on the HDMI output volume on stock, non-rooted Xoom 3.1.

ok so it is not just mine... Now the big question is if it is every xoom that has this issue or if it is just a selection?

Iv been asking about his for weeks. The sound output is terrible. Hooked up to my Sony system, same as OP says, no bass whatsoever. Same exact sound at same volume played through audio jack is giving my neighbor a heart massage.
Im really disappointed because I was hoping to output some nice tunes and even films but audio quality is unbearable.
Stock UK 3G on 3.0.1.
I demand answers :-D
Macbots drool as I XOOM through the Galaxy to my hearts Desire.

I'm glad to see this thread too. I've asked about this in other threads and on other forums and the only type of response I get is something like "I hooked it up to my tiny TV and opened the radio Disney app and it sounded just fine!" So it's good to hear people with ears noticing what I've been noticing.
That being said, from what I've been able to research it's either a problem with honeycomb's media player app or honeycomb itself. I've looked at the kernel code and while I did discover that the sample rate is hard coded to 44100 for the audio (with a TODO note in there to make it configurable eventually) I didn't see any errors that would cause it, unless it has to do with the fact that the kernel driver is forcing it to 2 channels but it's possible that honeycomb separates the sub woofer channel which is then discarded by the lower level drivers. Another theory is that they apply some equalization to the sound to make it sound decent on the internal speakers and that sound equalization gets applied to HDMI out as well (but not headphone out). What do you guys think?

Would be interesting to see how other HC devices perform in this area, sound quality, and video quality over HDMI. That might help to pin point weather this is a HC issue or a Xoom hardware issue.
The other HC devices that could be tested:
Acer Iconia Tab -- NO HDMI out
Galaxy Tab 10.1 -- NO HDMI out (proprietary dock connector for video out?)
Tmobile Gslate -- NO HDMI out
Asus Transformer -- Yes (Mini HDMI (Type C))
FWIW the Asus Transformer has the HDMI port is on the device and not on the keyboard accessory.
Xooms HDMI is listed as: "HDMI Type D (HDMI 1.4) connector"
I wonder what the quality of the Asus Transformer has on HDMI out, I wonder if it even does full mirror mode.
Wait, serioulsy only one other HC device has an HDMI out? Strange.
I wonder how GingerBread or Froyo quality is with HDMI mirror, are there any android phones with out of the box HDMI out with mirror?
My EVO has HDMI out but it doesn't mirror out of box, I think there is way with custom roms/kernels to get EVO HDMI mirror working.
Droid X has HDMI but no mirror unless you root, and install a special APK.
Are there any android phones with HDMI out mirror?

Greetings. Same problem with HDMI....workable, tolerable with EQ on amp. However....steaming music through Tune In radio or any other service is where I have a problem with the 3.5mm. Music Beta starts automatically. No matter what I do I can't get it to stop.
Suggestions...workarounds? Do I need to root the thing and remove Music Beta and go third party?

The Acer Iconia A500 does have micro HDMI out

Hi all,
Sorry to go against the majority here but connecting the Xoom to my Dell 21.5" HD Monitor with a Motorola Micro HDMI to HDMI cable is bringing me great results the picture quality is stunning. For sound i use the Audio out on the monitor to take the sound to my JBL powered sub woofer and 4 speakers and this also sounds great and i can also use the volume controls on the Xoom to change the volume through the speaker system. Are you all using the Motorola cable or another make?
Marc

I have the same issue. Horrible audio unless I use a 3.5mm Jack. I want good HDMI out... :'(

Same here. As soon as I started playing a movie through HDMI out I knew something was wrong. Came on here for an explanation or a solution, guess its down to a software limitation?

someone should bring this up in the Motorola owners forum. The forum mod there, Mmat, is really good about addressing issues the community brings to light and telling the software team

you can take another HDMI machine to test your tv. the HDMI line is also very important. my xoom is run well in my sharp tv.

I have the same problem with the sound quality that I get when connecting my WiFi only Xoom to my HT system. I tried connecting to a Bose lifestyle V30 and I get sound but it is just flat. No bass what so ever and only get sound from my center speaker. I tried a different HDMI input in the Bose system with the same result. If I connect the Xoom via headphone jack to RCA imput it woks just fine and get good quality sound.
I tried connecting to a Denon AVR-2308CI and I get the same result that I get with the Bose system. I have used 3 different HDMI cables, including a Motorola brand. No difference. Picture quality is great in all cases but the sound is just flat.
Now the question is: Is this a hardware or a software limitation?

[Q] Speakers/Docking stations

So hey, I'm searching for some good speakers or a speaker docking station to play music from my G2. Obviously there are an abundance of Ipod/Iphone speaker set ups. I was wondering what products you guys were using and what you think are the best for some outloud listening. Bluetooth streaming? Wifi? I don't even have a home computer, so I'm a little limited. Any feedback would help me out since it's almost Black Friday!! Thanks.

If you can't find a decent dock, you could get a 3.5mm to 3.5mm headphones thingy. Which is what I use for my iPod.
Plug one end into the phone, and the other into your TV. Win?
I must have been over thinking this, I'm gonna give that a go when I get home..only problem is my tv has weak speakers.This could be a good quick fix until I upgrade my system.

I tried this, but nothing..I have an Lg plasma and it dosen't have a specified headphone jack. I just plugged it into the two different spots that would fit the 3.5 mm. chord. One was for a controler, the other was rgb something. I might have done something wrong..Will it just play on any channel?

For my TV, it has the following channels for input
Antenna, AV 1, AV 2, AV 3, Component, RGB, HDMI 1, HDMI 2, HDMI 3
For my TV I have to use RGB to get any sound.
Also check you aren't plugged into the TV's headphone jack.
No its not, Maybe my next one will be.

[Q] Purchased cord HDMI sound problem??

Hello Guys,
I purchased a belkin micro hdmi cable yday... Mirroring worked pretty fine. Even played some demo 1080p videos on my g2x and they looked great. But the sound still comes from G2x instead of TV speakers.. I am sure tv supports sound from hdmi (i have a ps3 that works like that). I also couldn't find any settings that can change the audio output method. Is this the way it works i.e. (the sound never comes from tv??)..

Sound is most definitely output to TV over. There are no settings (other than manual resolution), it's all automatic.
Yup.. it worked today though with out me doing anything different.. I'l keep an eye on when this happens again. I am running only stock android but just rooted (for the setDNS app to revive my wifi ). So should be a glitch in the stock kernel(like many other problems) if it occurs randomly..

HDMI Audio Problem?

I am not rooted, totally stock. I have tried 2 different HDMI cables and both of them play videos to my LCD TV. But not the audio? Even if I play streaming or from the SD card, no audio. No sounds from any app. And yes the volume is turned all the way up on all volume controls.... media vol, tv vol. Any word on this bug? I have read others having the same problem.
There are posts about issues with certain hdmi cables not working correctly or not at all. There are different grades of hdmi cables which may be the reason. I recommend getting a cable advertised for droid. I got one from verizon store thats for the droid x and works great.
Gremlins are watching you...
Umm, I'm having the opposite problem audio, but no videos. Can play games and stuff and it shows (both audio and video) but if i try to play some movies or something, i get audio only. What's up with this?
Sent from my Droid Charge running Humble 2.2
Yeah I am having trouble too. I want to route the sound out the audio port and just send the video to the TV.
I personally think their is a bug. I have been reading up on this and it works fine for some but not for others. Over at the verizon forms their are a few reports about it. Some say certain cables work on certain HDTVs and then the same setup doesn't work on their friends HDTVs or bedroom HDTV. No consistency or solution, just hit and miss at this point :/

Need help getting a perfect audio recording on my SGS4G

Im asking all you guys to help me find best methods, settings, and tweaks to get the best possible audio recordings on my SGS4G. Im asking this not only from the devs here but from all the audiophiles as well.
The reason im starting this thread is that my partners iphone 4 just with the built in mic and camera has produced video and audio recordings 10x better then what this phone has. With great dynamic quality and no distortion or anything. I need broadcast quality recordings for this project to succeed. If i am not able to do so im either going to have to try to clone the SIM card and get a used iphone 3GS just for field work, or give up this phone and switch to an iphone 4. Either of which i really dont want to do. If part of the solution is to dump GB and go back to Froyo, then so be it.
Heres what i got:
1. Highly modded SGS4G with Valhalla 1.3.2, Launcher Pro Plus
2. 32GB class 4 Sandisk card
3. UV using the settings in the ICBINB therad (i tried some lower ones dsexton posted, but they made the phone very unstable)
4. Voodoo Plus sound app
5. i-Microphone (sound was horrible, more on this later) http://www.amazon.com/o/ASIN/B004XC6KHS/ref=nosim/betteraddons-20
6. Sennheiser E835 with XLR to 3.5 mono minijack adapter
7. Rec Forge and Hi-Q MP3 recorder (trying both, if you know of any with more features please share)
First off, im concerned that the custom ROM, kernal, and UV settings may be affecting quality. Any input on this would be appreciated. Ive tried OC, but 1.2ghz was never stable and 1.3ghz drained the battery too much.
I first off was looking for a good solution for face to face interviews, i found the i-mic (link above) to have good reviews, but when i bought it and tried it out, the recordings were horrible! Like someone was rubbing their fingers over the mic when talking. I tried gain adjustments in Voodoo and the recording apps im trying out, but nothing helped.
I plugged in my new Sennheiser using a XLR to RCA cable, with a RCA to mini jack adapter. The sound is A LOT better, but still there is a humming over the recordings, and they just do not have the dynamic quality that im hearing with the iphone recordings.
Are there any equalizer and sound processing apps for commercial or professional audio work out there?
Im at a wall here, any help to these issues would be greatly appreciated. Thanks in advance.
It's hard to tell exactly without seeing your set-up but it sounds like you have the following issue.
The XLR is a balanced connector. When you go to an RCA you are dropping down to an unbalanced connector and losing your ground. That is where the hum would stem from.
To eliminate the hum you would need a cable that converts directly from your balanced XLR to a balanced T/R/S (Tip, Ring Sleeve) mini jack. This mini jack has 3 separate contact points, separated by two plastic bands on the plug instead of one.
Ideally for broadcast quality you would need to run your Sennheiser E835 into some sort of mixer with a mic preamp. Then run the line level out from the mixer to the SGS4G. Your recordings would be crystal clear at this point.
I don't believe your issue is with the SGS4G hardware. I use the camcorder with the built in mic all the time and the audio quality is fine.
Hope this helps.
you don't need a balanced connection unless you are talking about long mic cables like over 5 feet long and equipment that is plugged into AC current. Balanced connections are for getting rid of the 60 cycle AC hum, basically.
If I was trying to record using a 4g I would think about using the usb input and some kind of analog to digital converter box. Here is a cheap one -- $25 behringer UCA 202 providing 2 RCA inputs-- it's about the size of a phone. and supposed to work on linux without drivers so maybe it will work on android. I have three of them and use them for laptops. They're pretty good at eliminating noise. I just don't know if the phone has enough power to operate the unit. You need a female to female standard usb adapter to connect the data cable to the converter and something to adapt a (short) mic cable to an RCA port. if it works you can use a dynamic mic like a AKG or Shure or some smaller dynamic mic and will get better recordings than anything built into any phone. It will be a little bit bulky but you'll still be able to fit the whole thing in your pocket. I should try it with my phone and see if it works but I need to get the female to female adapter. if the phone recognizes the UCA202 it should work just fine with a Sennheiser E835. My girlfriend uses a Sennheiser MD-431 for recording songs with her laptop and one of those units.
They also have usb mic adapters at places like guitar center. If you have the female to female USB connector you can take your 4g to guitar center or wherever and try their mics out before you buy anything.
@Nazcalito....great advice, I guess spending all my time on a control room board I hear the word 'hum' and immediately think 'where's the dirty gear, who's missing a direct box.' Haven't used a cable under 10ft in as many years. I'd be very interested to know if someone could get the USB audio/phone rig cooking on or s4g, that would be sweet.

Thanks for all the responses, ive been playing around with this and i do think the hardware is the biggest issue. I noticed the issue im having is that the built in mic is not turning off when using an external one. When using the external mic, i can tap over the back mic and get the feedback from it as well as the audio from the external mic.
Now the built in 3.5mm jack is a four contact TRRS plug, the RCA to minijack adapter is only two contacts. This would explain why the little plug in mic was getting all the feedback. Though even that mini i-mic was a TRRS plug like the headset thats included with the SGS4G. Why is the built in mic not turning off?
Nazcalito, your suggestion of the USB audio interface may work, i did consider a microphone with a USB connection, though i could not find any accounts of this working by simply plugging the mic in to the phone with a USB to microUSB adapter, and didnt want to take the chance. Though i like the converter box you showed a pic of, i could just velcro it to the back of the phone to make a mobile unit. I'll probably buy one if youre able to confirm it works. Again would i have the same issue with the internal mic not turning off when using this?
One thing i ordered was something called the headset buddy, its a TRRS male plug that splits into two separate minijacks for headphone and microphone. Im hoping this will solve the problem.
http://www.amazon.com/o/ASIN/B002SK66OY/ref=nosim/betteraddons-20
Another concern is the pinout of the SGS4G. Ive found diagrams for the i9000 that shows the mic and ground contacts swapped, and others with the regular mic as the last pin that claim they are for the Galaxy S2 and SGS4G. Anyone can confirm? This might explain the internal mic staying on.
http://pinoutsguide.com/CellularPhones-P-W/samsung_galaxy_headset_pinout.shtml
http://pinoutsguide.com/HeadsetsHeadphones/samsung_i9100_headset_pinout.shtml
As well should i have all the options in Voodoo turned on for this?
Ya know, i wish i didnt order the headset buddy already, i would have tried this:

The adapter did not help, the internal mic is still staying on.
That's not good. I have a similar problem occasionally with headphones not muting the speaker when used...I have to wiggle the plug a little until it mutes. The contacts are definitely a little touchy.

USB Audio for TF700

Hi,
I've been looking for a solution to use a dedicated USB soundcard with my TF700, because the sound quality from the 3,5mm analog out isn't loud enough, the quality isn't great and I hear lots of intermittent "hiss" noises when I'm watching movies with DTS sound (whatever the video player I use).
The main problem is the loudness, since I'd like to use the tablet to watch videos i.e. in a plane.
I was thinking of an external USB soundcard like the Asus Xonar U1 or U3 to connect to the dock's USB, but I'd like to know if anyone has tried it before.
Preferably, I'd like something with a dedicated headphone amp.
I have a HiFimeDIY Sabre DAC that kind of works when I plug it in the dock, I hear sounds but with lots of popping and cracking.
Using the USB Audio Player I could make the tablet work correctly with the DAC, but that one only works for music, and their custom driver doesn't work with other apps.
Any help?
(sorry if I posted in the wrong section)
An update:
I went to a store and tried a Xonar U3 connected to a TF700+dock. Same thing as with the Sabre DAC I tried earlier.
Whenever I play something, the sound is "recognizable", but it's mostly made of popping and cracking.
It sounds the same as is I was used the Audio Player before applying the proper settings (force 1-bit, 16bit sampling, 4k buffer).
This seems to be a driver issue. I heard Samsung phones/tablets work flawlessly with most external USB DACs, so this is a real shame.
