Sound problem (only 24bit 48000Hz supported?)

Environment

• OS/Distribution: Ubuntu 20.04 / Windows 10
• Desktop Environment: Gnome 3.36 / Windows
• Hardware: AMD Ryzen 5 3400G with Radeon Vega
• Exact Version or Commit Hash and Installation Method: v1.2.1 build from sources (Ubuntu) / 1.2.1 (Windows)

Describe the bug I've noticed that Chiaki uses only 24bit 48000Hz stereo sound. When on Ubuntu running from Appimage sound is fine, I wanted to run with VAAPI driver without success from Appimage, builded app from source gives me VAAPI but with error about sound: "E] Audio Format with 2 channels @ 48000 Hz not supported by Audio Device", same issue is on Windows using wireless headphones that support only 16bit 44100Hz sound

To Reproduce Steps to reproduce the behavior:

1. Run Chiaki
2. Connect to PS4
3. No sound produced

Expected behavior Sound should play with other sound settings (eg. 16bit 44100Hz, 32bit 48000Hz, stereo, mono, 5.1 etc...)

Hmm... This doesn't sound by the error given that it's Chiaki's fault per se. Check what sound card - or "sound card" - you have. It may be just that you have probably integrated thing that can't go beyond 16bit 44100 Hz or whatever.

The reason why it only uses 16bit 48000Hz (not 24bit) is that this is the audio format that is begin sent from the PS4. This is then just put in a standard QAudioOutput which is supposed to handle resampling somewhere else.

I am curious about your audio hardware, could you please describe in detail what you are using? For example post the output of pacmd info on Linux if you use PulseAudio.

Since you are already building from source, you can also try to just remove this line here and see what happens: https://github.com/thestr4ng3r/chiaki/blob/master/gui/src/streamsession.cpp#L273

Here's the output log: soundinfo.txt

Just to be clear: I don't care if it'll be 16/24/32 bit or 44100/48000Hz, I'm no audiophile and don't have super HiFi sound system, anything above 16bit 44100Hz is going to be irrelevant to me and my speakers ;)

This does nothing....

Strange, if I run Appimage version then in log there's info about soundcard: Audio Device alsa_output.pci-0000_08_00.6.analog-surround-51 opened with 2 channels @ 48000 Hz, buffer size 15680 When i run compiled version there's no info about soundcard, as if sound card don't detected.

Maybe you are missing the libqt5multimedia5-plugins package then. The AppImage comes with its own libraries.

Yes, they were missing, audio now works oob. Thank's thestr4ng3r !
