Hdmi audio doesn't work on db820c


#1

HI,

I tried 4.14 kernel branch. Hdmi audio doesn’t work. Can someone please let me know, is it tested?

Thanks,

In my case, HDMI audio was glitchy (using the latest 201 Debian release). The solution was:

[1] Reinstall PulseAudio
sudo apt-get -y remove --purge pulseaudio
sudo apt-get -y install pulseaudio
sudo apt-get -y install pavucontrol

[2] Edit file “/etc/pulse/default.pa” and include “tsched=0” (after load-module module-udev-detect):

load-module module-udev-detect tsched=0

[3] Reboot

Reference :
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling

(look for “Glitches, skips or crackling” in this reference)

Note: maybe, step [1] can be skipped (I just tried it first). Steps [2] and [3] may fix the issue.

I hope this helps.
