Only left sound channel is recorded from microphones on some new samsung devices (2022-2023 models)
Hello, with some new samsung devices, from friends, they have z-flip 4, s22 and from me, with my s23 ultra, we have only the left microphone working and others hears us on the left side with very low volume at 50%, and some others friends with their galaxy listed above, they don't have this issue.
didn't notice if it is not stereo, but very low volume with my s21 even with mic level set to 100% (normally a very bad idea on my Pixel phone indeed). may be related?
Oh, I'm able to reproduce this now, I'm not able previously, but it suddenly appeared. Very lowd volume and only left side. Very strange, no idea on how to resolve it.
@bear101 colud you please expose listing and setting of input devices from opensles to c-api if there is no such? i can't remember if they exist in c-api? In that case we would be able to make a selector and let user to choose needed input source.
@beqabeqa473 On Android (and iOS) there's not really a list of source devices like on e.g. Windows and Linux. On Android I just create two device: a default device and a voice communication device. You can find the code for this here.
On iOS I do something similar w.r.t. creating sound devices but from the UI application I'm able to change audio routing. Therefore iOS does not need a list of sound devices.
Yes, i understand that there are no list of devices, but on android there are input sources for camcorder, voice communication, raw unprocessed, voice call, default and others. I meen that.
@beqabeqa473 @bear101 @CoBC Same issue with samsung galaxy a73 here, microphone gain is 100% but my audio volume is still very low for others and it can be heard hardly. When its 50% it cannot be heard.
It appeared because the newer samsung phones don't support Recorder samplerate of48KHZ, that's why, so by setting it to 24KHZ it fixed since newer samsung phones have a very high quality microphone
Why would a high quality microphone record at 24KHz? 48KHz would make more sense.
