Hi I use qubes 3.2 and sometimes I listend to music using youtube on a user vm. Now I had the following problems: the sound was often distorted, sounded like overdriven pre amplifier, but if one stops the sound source (youtube in browser, press pause) there was a trailing 1 second of destorted sound. Like if there was a buffer that was not served in time and wants to empty out.
So I looked around and found that there is a configuration to be changed: take a terminal in dom0: sudo su (now I am root) vi /etc/pulse/default.pa find a section and modify like I did: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so ##modified 01.11.17 #load-module module-udev-detect ##against glitches load-module module-udev-detect tsched=0 ##-end-modified 01.11.17 So add tsched=0, this disables PulseAudio's timer-based scheduling and uses the classic interrupt-driven approach why? see: http://0pointer.de/blog/projects/pulse-glitch-free.html now say :wq to your vi then in your root shell of dom0 say pkill pulseaudio and it restarts, now without distortion or glitches. My audio hw is: Creative Labs EMU20K1 (Soundblaster X-Fi Series) Having a decent sound board one wants no lowfi destorted sound... So have fun with better audio. @qubes-os developer. Maybe, you should patch the file /etc/pulse/default.pa for dom0 accordingly. Cheers, Ludwig -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
