Will not play sound via HDMI using 48000 Hz sample rate

[Jarno Suni]

Does not play sound when playing file that has 48000 Hz sample rate via sink output:iec958-stereo. This is when using proprietary nvidia-340 driver; when using nouveau driver, HDMI is not even recognized (Bug #1844129).

Note that the device (HP 8510w, having NVIDIA Quadro FX 570M graphics adapter) does not have real HDMI audio, but audio is somehow wired from motherboard's S/PDIF to HDMI explaining the sink name. Anyway, in the attached AlsaInfo.txt there is a device "Node 0x02 [Audio Output] wcaps 0x30311: Stereo Digital" that has "rates [0x60]: 44100 48000".

Workaround:
Set
alternate-sample-rate = 44100
in /etc/pulse/daemon.conf and restart pulseaudio

When pavucontrol is not running, it depends on sample rate of playback, whether or not the sound is audible:

$ speaker-test -r 48000
not audible

$ speaker-test -r 47999
audible

Status changed to 'Confirmed' because the bug affects multiple users.

I tried this by 20.04, but could not get sound via HDMI cable work, except once, even if I had sample rate 44100 set in daemon.conf. I wonder what is wrong. TV tells: "unknown audio signal, check the source."
