I have problem with playing sounds in more than one program. In example, I have enabled YouTube in FireFox or any game and when I'm trying to listen music in VLC Media Player, I'm getting this error:
Audio output failed: The audio device "sysdefault:CARD=PCH" could not be used: Device or resource busy.
I tried to use Pulseaudio, but the quality of audio was poor and there was no bass (or that was distorted).
My sound cards in /proc/asound/cards:
0 [HDMI ]: HDA-Intel - HDA Intel HDMI HDA Intel HDMI at 0xc3610000 irq 49
1 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xc3614000 irq 48
I have latest version of ALSA, same with the rest of the programs. I tried to reinstall ALSA.
I do not know if it has any connection with the problem, but the .wav files in any player are distorted too (.mp3, YouTube music, sounds on games, etc are ok).
Thanks in advance for your help :)
