[Q] Problem about AVRCP in N1

My phone is HD2 and installed the rom New Nexus One Android 2.2 Build FRG33 [ mccm v1.5](8.9.2010)
I found that i just couldn't use the buttoms on my bluetooth headset when im enjoying music.
what should i do with this problem?
thx for ur help!
I get this problem occasionally when I link my N1 w/ my car stereo. The controls don't work etc and it's not in audio streaming mode (ie. it's probably only using the Phone bluetooth profile and not the stereo audio profile as well). What I usually do is go into bluetooth settings, long click the device, and uncheck the bluetooth profiles. Then I recheck those profiles and reconnect the device. This usually fixes it. Of course, your problem could also be related to this HD2/Android hackery...

Bluetooth headset compatibility

Hello guys, anyone use a bluetooth headset? if yes, what brand is it? i use LG tone+ that support bluetooth 4.1, a2dp and apt-x, but the problem is the sound frequently become distorted, especially when my kenzo far enough from bluetooth headset (50 cm +). Is the problem with headset or rom i used? i use miui 8 dev cn. thanks for help.
hey, i think its headset related. im using a AudioMX Bluetooth Over-Ear headset and it works within a reach of 4-5m. after that distance i have problem with audio distortion.
I have a sony SBH60 and it works flawlessly. No distortion at all, and little to no "audio lag" (I mean audio/video sync), at least I haven't noticed while watching classic youtube content, I don't use my phone for movies or TV Shows.
For me I am using Samsung level U and everything works well. Besides, I have a portable bluetooth speaker too (china brand) and also works.
what rom do you use guys? i use miui dev cn official. thanks.
I'm using latest xiaomi.eu rom
Sorry for the late reply, I'm using 8.1.3.0 Global, always kept my phone up to date, no issues so far.
Also tested with my in car Pioneer MH380, a Logitech MiniBoom (UE), and a MPOW Bluetooth transmitter.
I've never had any issue with bluetooth whatsoever, maybe a clean install could help.
Hi, anybody having their sounds lagging every 10-30 seconds? I'm streaming via bluetooth to my car head unit and the sound keeps disappearing about a second and it's pretty annoying. and only this phone having this trouble. Update/clean install doesn't help. I'm using global dev.

Bluetooth audio re-connection fails with BMW.

Hi all,
ROM is MicroG LineageOS 14.1 (Android 7.1.2)
After my last visit to maintenance, my Mi4c cannot re-connect to the audio channel in my BMW X1 (quiting the car / going out of range). The Tel channel reconnects OK. Dunno if BMW did a software update.
I have tried several things to make it work but the only one that solves this problem is to reboot the phone before it connects to the car's Bluetooth.
It seems like a process is making the Bluetooth audio channel busy.
Is there a way to see which app could lock the Bluetooth audio channel ? Is there a way to do a sort of clear cache/kill the app preventing the connection ?
Thanx for your ideas.

Best settings for ViperFX

Hello, I'm totally new to this and I'm searching for some help.
I've recently installed Hal9K mod for my android head unit. It is PX30, and I have Android 9.0. I also have aftermarket speakers (Hertz CK 165) and a subwoofer (1000W).
So I'm asking what are the best settings for ViperFX? Should I instally any IRS files? Should I change the settings for headset, or for speaker, or for bluetooth? Should I thick something in the settings before the Viper stars working automatically everytime when I play some music?
Thanks for your help.
I also am interested in what others use for V4A settings. So far my audio is either sounds like it's in a can or I can not change the directional audio..

Switch Audio outuput with Android Auto Wireless

Hello,
I have a Galaxy s9 under Android 10 and One UI 2.5, in Bluetooth it is possible to choose the audio output of my applications.
But when my phone is connected to my car in wifi (AA Wireless) I can't change the audio output to another device. The output is forced on the wifi
I have already tried applications like Lesser AudioSwitch but it didn't work.
Does anyone have an idea ? (custom ROM, Custom Androit Auto ?)
I am having the same issue for my pofo F3. If there any solution avialable ?
I am using a 3th party screen for wireless anduod auto, it was great but the build in speaker for the screen is horrible. I am looking for a solution to route the audio to my car's Bluetooth. Is there any suggestions on this ? Tried to disable the audio access to the wireless AA auto screen but doesn't work.
