Describe the bug

I'm sorry, I'm not proficient in English, the following is a machine translation
Hello developers.

The problem I have is that after starting scrcpy without adding any parameters, the computer side does not receive the content of the audio forwarding (no sound from the phone), the phone speaker is working properly, how can I fix it

Hmmm, createAudioRecord() was modified on your vendor rom, it does not behave like AOSP.

Out of curiosity, could you test the new playback capture method in #5102?

嗯，在您的供应商 rom 上进行了修改，它的行为不像 AOSP。createAudioRecord()

出于好奇，您可以测试一下 #5102 中的新播放捕获方法吗？

Hello, I downloaded and used scrcpy-win64-v2.5-34-gb417c5441, and set the parameter playback, scrcpy still has no audio forwarding.

Hello, I changed to an Android 11 ROM, scrcpy can run normally, it is true that the previous ROM has a problem that causes it to not work normally
