[Q] MHL-HDMI TV(without MHL) No output - General Topics

First to say, this is a bit long, but explains exactly what is my problem and what am I doing, I really need help, please. Thank you,
Today I bought hdmi (Male-Male) cable and MHL 5-pin adapter for my Xperia Z1 Compact. And I have a really weird problem. So I set up everything the way it's supposed to be, connect hdmi cable to TV and mhl adapter, charging cable to adapter and then connect adapter to phone, also I set correct hdmi channel on TV. And, I get notification about MHL connected, but there's no any picture or sound on TV. Also, phone randomly stops charging, however mhl notification still stays and screen stays landscape, until I switch to another program on TV or unplug cable. Another weird thing, if I play any format of video in any player(even stock one), video stops every 4 sec and I have to manually press play every time(it's not performance issue though, I can play unoptimized games for qualcomm like GTA SA with same amount of framerate as if I played normally) and sound from video can sometimes go out through phone speaker(and it's not supposed to, instead should come as hdmi output on TV). And here some of the facts:
-My charger and cable normally works
-Without charger connected to mhl adapter, I dont get any notification, so charging part is fine
-If I unplug hdmi cable from mhl adapter, I dont get random charging interrupts, phone charges constantly
-I have stock 4.4 Kitkat Android, no system applications deleted
-My tv is from 2005, Panasonic, without mhl but has 2 Hdmi slots- 720p, in case TV means anything
I have 3 guesses that came to my mind: software issue(like bug or something), unsupported resolution(maybe if phone doesn't recognize TV's 720p and instead sets to full HD(but then there wouldn't be charging issue and probably video pausing issue too) and lastly, broken adapter(To mention, it's right type, 5 pin, so it could only be literally broken inside-loose, but it seems quality and if it was loose there would still be some kind of output on TV, during normal charging period)
Can anyone give some solution...? I can't find any similar problem to mine, so I have no idea what could be the cause.

[Q] HDMI output stopped working

I uses to be able to watch TV show stream and my videos on my TV via the g2x HDMI out even with root and eb and cm7 then I went back to stock for a bit and the HDMI stopped working on the same TV using the same cable now all I get is a blank screen and no sound but it says playing on other screen so it obviously recognizes the cable... has anyone else come across this?

Any possible reverse connection via HDMI

Is it possible for the O3D to accept an HDMI signal? i.e. plug the phone into a hdmi output and display a movie, or game on say a ps3?
Don't think so.
Not possible, the phone has a HDMI output, not input. Different things and that is fully hardware based, meaning no software could do that.

HMDI connected Android TV Box

Hi folks,
I´m not quit sure if it is an Android problem or a problem with my box.
When I switch off the TV when the box is connected via HMDI the box goes "off" (switching off sound for example) is there a way or setting to keep it on? So I can switch off TV and keep spotify for example on?
Yes!

Yes! I use my Chromecast in this way. What you need is an HDMI pass through device, like a stereo tuner. I have both a Chromecast and Roku dongle plugged into the HDMI ports on my tuner (it has a total of 4 hdmi ports) . A single HDMI cable then runs from the tuner to the TV. The sound comes out of my stereo speakers, not the tv, and I use the stereo's remote control to switch inputs (the TV itself is never changed from its HDMI1 input). This allows me to listen to the audio without having the TV turned on. Tuners with HDMI pass through can be expensive, but I got lucky and found one, virtually brand new with 4 HDMI inputs, at my local Good Will for $65.

I found a solution which might work. You need to "block" pin 19 from HDMI which reports powersaving / energy modes. I just need to try it at home

Did you ever get this to work?

Question My P7P just chokes on USB-C wired ear pods.

The phone (running the latest 13-beta and rooted) just can't tolerate USB-C wired ear pods. Audio drops out after a few seconds--even tho the app shows it's still 'playing'. Sometimes I have to stop the app, un-plug and re-plug the pods to get it to play in the first place. The notification area will show that wired headset is attached, but audio just won't stay on.
This morning the phone locked-up while trying to get them to work and I had to hard-reboot.
This happens with a brand-new pair that had a native USB-C connector, and an older pair I'm using with a USBC-to-miniplug adapter.
My bluetooth OnePlus pods work reliably every single time. Tried with two different audio apps, still no love.
Any thoughts?
Do you have File Share as Standart on USB Connection?

Wow. You might be on to something! Under USB Preferences, "USB controlled by "Connected device" is selected and "Use USB for File transfer / Android Auto is selected--but greyed-out so I can't change it. Am I missing another setting or something...?
I Heard about this Problem before. But i think IT got fixed in latest stable Firmware....
USB-C to headphone adapter music stops with locked screen...and can cause an OS crash?
Would some of you smarter people please help figure out what's going on? I/you can then file a bug report which won't result in it being closed due to their misunderstanding. The primary issue is that music stops playback when a USB-C adapter...

[HELP] USB-C dongle DAC constantly disconnecting

Phone: Poco F1, DAC: Jcally JM6 Pro
I'm playing music, it stops and there is "Preparing USB device..." toast. Sometimes it reconnects a few seconds later and I can start playing music again, sometimes I need to reconnect it physically. Sometimes it disconnects once in 5 minutes, sometimes it starts disconnecting every 5 seconds. Upon disconnection sometimes the music player crashes and a few times even the whole system went into a restart.
It's not the fault of the music playing app, I tried many and whether the player has direct USB access doesn't make a difference. The phone's USB-C port is new and clean. The dongle works perfectly fine on any other device. The connected earphones make no difference. The DAC is relatively weak and it should easily receive enough power from the port.
I tried 3 different Android 13 ROMs with different kernels and same things would happen. I went back to stock fastboot rom, flashed Android 12 PE+ on top of it and initially it was working fine but then disconnects started and I couldn't figure out the trigger. Interestingly, upon reflashing the ROM, disconnects would happen even in the beginning.
The only ROM that solves my problem is stock MIUI A10 ROM, no disconnects whatsoever. But it's old and not that usable. Anyone have any idea what's causing this and what can I do?
May be phone's USB port your DAC is plugged into is a low-power one. Hence try to add an externally powered USB hub between your phone and your DAC. This will supply ample power to the DAC that the underpowered USB port just can’t deliver.

Thanks for the response. As I said, the DAC is relatively weak, people drive dongles over 2 times as powerful with no issues with this phone. Also, everything works flawlessly on the old MIUI fastboot a10 ROM but it's not good for daily use.
