Title:
[Intel Broxton HDMI, Digital Out, HDMI] Pulseaudio detects output but
produces no sound on an HDMI TV until power cycled.
Status in linux package in Ubuntu:
Incomplete
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
Upon bootup, the HDMI output connected to a Samsung TV shows up as an
output. If this output is selected and a sound test run (either using
the GUI or using aplay /user/share/sounds/alsa/Front_Center.wav) no
sound is heard. Pavumeter does however show sound coming through.
I found that sound can be fixed by allowing the display to sleep,
waking it up, and then restarting pulseaudio (pulseaudio -k). After
that sound output through HDMI to the TV will work until rebooted.
The fix can be succesfully scripted as follows:
xset dpms force off
sleep 1
pulseaudio -k
The machine is an Intel NUC6CAYH, connected to a not particularly new
Samsung 42" TV using an HDMI cable, running a fresh install of Ubuntu
16.04.
In earlier attempts at fixing the issue I set pulseaudio to never let
the sound device sleep (commented out load-module module-suspend-on-
idle in /etc/pulse/default.pa), and also set the default sampling rate
to 48000 (default-sample-rate = 48000 in /etc/pulse/daemon.conf). Not
sure if these settings contributed to the fix, but they are not
sufficient on their own.
