Hi, this isn’t a new issue so I don’t believe its related to upgrading to kernel 5.8.
Whenever i play a video on YouTube or Reddit etc, the video plays but sound is not present for 5 seconds of playback. While trying to troubleshoot, I tried rewinding the video to a second after the video starts but the audio issue still remains. It isn’t browser specific either, tried both Brave (chromium) and Firefox.
Can anyone help? If more information is needed to troubleshoot, please let me know.
is only browser audio delayed or is audio from within system also delayed?
please post system information
inxi -Fxxxz
and Pulseaudio information
pulseaudio --dump-conf

The issue only seems to occur when using HDMI audio. Audio direct though onboard sound works fine.
pulseaudio data shows there is a custom user configuration file ~/.config/pulse/daemon.conf
suggest you edit that file and add this:
flat-volumes = no
and restart pulseaudio to reload configuration
systemctl --user restart pulseaudio
default pulseaudio configuration setting flat-volumes = yes also uses these additional configuration settings
enable-deferred-volume = yes
deferred-volume-safety-margin-usec = 8000
deferred-volume-extra-delay-usec = 0
this will cause an 8 second delay in audio level changes
there is an explanation about how deferred volumes work in man pulse-daemon.conf (line 330)
but this feature does not work well, so many distributions change configuration to ‘flat volumes=no’
and next version of Pulseaudio v14 will have this default setting change
PulseAudio 14.0 release notes (draft)
Thank you, this has helped. However it only reduced the delay. It is now 3 seconds instead of 5. So I manually added “deferred-volume-safety-margin-usec = 0” and this fixes the issue inconsistently. Anything else I could do?
The only other thing I see that might cause a delay problem is:
resample-method = soxr-vhq
suggest try other resample methods soxr-hq or speex-float-5
man pulse-daemon.conf has more information about resample methods
- terminal alsamixer
- F6 and select your generic sound card
- disable auto-mute
