[Q] Using USB Speakers with Transformer - Eee Pad Transformer Q&A, Help & Troubleshooting

Hiya,
I got hold of a pair of logitech Z305 USB speakers to try on my Transformer. When I plug them in, the light on them turns green, and the volume buttons on them work to increase and decrease my volume. However, I don't get any sound out of them; sound still comes through the tinny asus speakers!
So, is there any way to change where sound is output too on the tablet? I am aware that I could get a 3.5mm cable and plug that in to the speakers/netbook as well, which should work, but I was wondering if there was a more elegant/less cable-intense solution?
Thanks,
James

It's important to understand that USB speakers (and usb headphones/microphones) are not simply speakers/headphones/mics. They are really little USB sound cards that happen to have a pair of speakers or mic hoooked up to a small power amp built in to them. They do not magically transfer the output of your built-in sound card to the speakers over USB. (like plugging in an 1/8" stereo plug would). So, unless the transformer has support for the standard USB audio protocols used by your USB speakers (and I doubt it does) you won't hear anything out of those speakers. Additionally, since the transformer doesn't know what to do with the USB sound card you have plugged it it doesn't recognize it as an alternative sound output (like A2DP bluetooth audio) and will continue to pump sound out of the built in speakers.
Your best bet is going to be to use standard speakers with an 1/8" jack or a set of expensive bluetooth speakers. Now, will the 3.1 upgrade bring support for usb speakers and headphones? Maybe... I haven't seen anything to indicate one way or the other aside from the very nebulous statement that 3.1 will provide USB host "support".

Sound while plugged into car charger

Hello!
When I plug my Touch Pro into an active Adapt carholder the sound output of my touch is forced to the charger (no sound output anymore on my mobile).
Is there any way around this? Any registry setting?
Or maybe remove some of the pins from the mini-usb connector on the charger?
Try getting HTC's official dongle which plugs into the USB port and gives you several connectors;
USB for charging
3.5mm headphone socket
2.5mm mini-headphone socket
USB for HTC's original supplied headphones
If you use this, you can plug in headphones at the same time as charging. I use it to route sound through to my car stereo so I can use the phone as an MP3 player and Sat-Nav.
If you don't use the headphone sockets, sound still comes out through the main speaker on the phone.
Hmm I have one of those, but the car charger I use is a slide-in holder, so there won't be much room for the dongle
Microphone unuseable when plugged into stereo
I use the usb dongle adaptor in my car to push sound through the stereo, however this disables the HTC Touch Pro microphone so although I can hear people calling in (through the car speakers) they cannot hear me.
I think it is because the phone thinks the headphones are plugged in and that I'd use the headphone microphone.
Does anyone have a tweak which would allow the phones microphone to remain in action when using the dongle?
Many thanks

I don't have that problem at all, my phone's microphone works fine while using the USB dongle with a 3.5mm jack plugged into it, connected to my car stereo.
Are you using HTC's official dongle, the one with the 3.5mm, 2.5mm USB power and USB headphone sockets?
It works fine for me!

[Q] How do I record from an external audio source (Microphone/Line-In)

Hi, I hope you can help me out.
I'm trying to record some audio through the 2-in-1-combo-audio jack.
Everytime I connect an external music player to the transformer via audio jack, the transformer does not recognize that somethign is plugged in, but it thinks I want to use headphones (jack as output).
How can I swith to mic mode (jack as input)? Do I have to use a special asus app or is there a good app in the market that can do this?
Thx in Advance!
I doubt that you be able to do that
Why?
The specifications are very clear:
1 x 2-in-1 Audio Jack (Headphone/Mic-in)
Or do I understand this wrong?
I would guess that it will only recognize the microphone when it is connected via a 2 ring connector like a headset/mic combo. A mic by itself would not have a connection that the hardware could recognize.
I am only theorizing based on my experience with with an iPhone.
Hope you like mono recordings...

Maybe it can be achieved after 3.1 and with USB?

Yeah I think you are right, a member of another forum told me the same, that he plugged in an Apple Iphone Headset and the external mic on the headset worked. I also have such combo headsets with the same plug but they dont work. The internal mic still was still active. Could anyone please try to connect your headset and post if
1) the external mic will work
2) the internal mic gets deactivated.
3) and what headset is beeing used?
THX!
Hope you like mono recordings...

I will only use it to record voice, so thats ok.

Maybe then with additional Accessories, I hope to do this with the standard audio jack, which should be able to do that... at least according to the specs.
Quite possibly it would just need software to work. Since it is in the specs, a headphone/mic combination should work. I noticed tigerdirect was selling a combination headphone/mic as a bundle with the transformer.
You're going to want a 4 pin headset (mic/left/right/ground), which is how modern devices do dual input/output audio. Standard mics are 3 pins (L/R/Ground) just like normal headphones, therefore the hardware cant differentiate. Now the issue may come up on the arrangement of the headset pins. Prior to the iPhone, the standard 4 pin headset was configured in such a way that they would not work as normal headphones in devices that weren't meant to support headsets but Apple (or someone around that time) came along and switched up the order so that a 4 pin headset would be backwards compatible with a 3 pin jack -- a superior setup I say hesitantly, with the only con being that old headsets and new jacks are incompatible and new headphones with old (4 pin) jacks. If Asus is using the old standard, then an iPhone headset would not work and if Asus is using the new standard, then an old headset would not work.
Finally, it works!
I wanted to use an external audio source. You have to connect the cable first to the transformer, and AFTERWARDS connect the other side to the audio source. Only in this order the internal mic becomes deactivated.
If there is any signal on the cable while plugging it in into the Transformer, the internal mic is still active. I've attached my "cable construction".
The side with 4 pins goes into the transformer the 3 pins into a mono audio source (normal Headset Output). This works fine for me since I'm only recording voice (mono channel).
Problem solved!

[Q] Question on microphine/audio output

I have been researching online about using car aux-in cable for making phone calls.
I heard that some phones work and some do not. In those cases, when it doesn't work, it means that the person in the phone cannot hear what you say, because by default the mic is muted when something is plugged in to the jack.
With HTC Sensation, does this happen? Is the phone mic muted when a headset/aux cable is plugged in to the phone? If yes, is there any workaround? What is the general solution to make phone calls via aux cable?
I heard that some people might use the griffin cable with mic, but since my aux port is located where the shifter is, I am not sure how the quality would be. Any idea?
Thanks

well, i hope this answers ur question
i have made calls/received calls via aux (when im listening to music in da car n get a phone call i dont uplug it, just answer)
i talk thru the mic normally and i hear the other person from tha car speakers.
so i guess the mic is not muted
From previous experience - though not with Sensation, as I'm all blue-tooth now, the following was true
If you plug in a normal 3.5mm TRS jack (stereo headphone / line-in / etc) the phone detects it as headphones and not headset, so the device realised there was no "in-line" mic, and used the phone's microphone itself.
A better option (which I did) was to fashion my own lead - using another HTC headset, but removing the two earphones, and soldering the cables to an in-line socket. This worked well, because I had a microphone clipped to me, with remote control for music (don't want to touch the phone when driving now, do we!!) and the stereo audio feed back to the car speakers. Cost me about £3 in total, including the second headset.
I would imagine this to be the same for the Sensation too, as all these sockets have various detection mechanisms, to make the right things happen, depending on what you connect.
Good luck, and safe driving!

No 3.5mm Stereo Jack Output w/ Aux Cable w/o Hi-Fi Mode Enabled in ICS

I've been using a Motorola for the past 2 years and upgraded to a faster dual core (Huawei Ascend P1 LTE U9202L), and faster quad core (Blu Quattro HD 4.5 D450) - both run on ICS 4.0.4, stock ROM (but rooted), but both have the same problem with the 3.5mm stereo jack. I did not have this issue with my previous phones and have no idea why the behavior is so dysfunctional. On both devices, plugging in the 3.5mm aux jack into my stereo does not work. It does not detect as a headset and just outputs through the phone speaker. However, on both devices, plugging in ANY headset, and the phones detect and output audio appropriately.
However, plugging in a 3.5mm aux cable into a car stereo does not work at all. It won't even show the headset icon in the status bar. I've used several cables, in several different cars, but all no love, while iphones and other phones in the house work just fine. This is with both 3 conductor and 4 conductor stereo cables. With the Blu Quattro however, I found a setting in Sound called "Hi-Fi Mode" which enables the phone to specifically output audio through the 3.5mm jack to an external stereo system. If I plug in the aux cable to my car, nothing goes. Enable Hi-Fi Mode, and then I magically get audio output.
What in the hell is Hi-Fi mode and is that something standard to ICS? Is there a software fix where I can just plug in the stereo aux cable like every other normal phone out there, and have it automatically output properly instead of enabling this funky Hi-Fi mode? It's really annoying because I need to use this device for work as well where we sometimes use the Square Reader. That thing won't even detect on either phone!
At the moment, I'm considering buying one of those USB to 3.5mm jack dongles that I've seen phones come with, that don't have a 3.5mm jack. In the meantime, if anyone has any suggestions, I'd really appreciate it.
Many Thanks in Advance,
Chuck

USB DAC and USB Mic

So, I have an interesting issue. I think it is a deep seated Android one, so I'm not liking my chances but......
Setup:
Samsung Galaxy Tab S7+ ---> Dell WD15 USB dock (I have also tried a plain old USB-C Hub)
Android 11, with latest updates possible.
When I connect my USB DAC (a Grace SDAC) which connects to my headphone amp - it works perfectly. Android shows the DAC in 'media' as a "Headset"
When I connect my ModMic Wireless microphone's USB dongle, the DAC stops working and switches to the tablets internal speakers
When I connect a 3.5mm mic to the doc's headset 3.5mm jack the DAC stops working and switches to the tablets internal speakers
Some apps dont seem to work with the modmic wireless. Some dont work unless I plug in the USB dongle while the app is running - That's app problems, I get that
All Apps seem to support using the mic via the 3.5mm jack.
The opposite is also true, if I have a mic connected (USBor 3.5mm) then connect the DAC, the DAC works, but the mic stops and switches to the tablet internal mics.
What I seem to have found is that it is impossible, in android, to use both a USB DAC and any kind of microphone.
Has anyone had this kind of thing working before? Is there something I can do/try? are there logs or something I can look at which might help here?
I'd love to get this working, but I dont think thats possible... I would like to know why or see some real detail behind why it won't work..
Thanks!!
