No sound over DisplayPort

Sound was OK over DP for months until few weeks ago.

Now only working over HDMI.

It can randomly work over DP (but happens very rarely) by switching my cable between HDMI<->DP but I can't find a consistent way of making it happens.

My configuration :

Sound working :
Asrock H610M-ITX (using intel i3 12100 iGPU no other graphic card) connected to an Onkyo AV Receiver (TX-NR7100) with HDMI cable, AV Receiver connected to TV with HDMI cable.

Sound not working
Same except there is an Cable Matters 102101-blk DP to HDMI adapter connected between Asrock and the same HDMI cable going to the AVR.

What I've tried so far :
Switching from pulseaudio to pipewire -> no change
Changing the Cable Matters adapter by a new one -> no change
Downgrade Kernel to try few older ones -> no change
Factory Reset TV and AVR -> no change
Live CD (Ubuntu) -> no change
Updating MB bios -> no change

Am I missing something or could it be an hardware problem related to MB ?

Re: No sound over DisplayPort

Hi,
Have you installed/check in pavucontrol the profil in the configuration tab?
Have you checked in alsamixer the key F6 (change device) and keyboard keys M ([un]Mute)? Maybe the device is set off/Mute.

On my PC I have two sinks. When it is playing, one sink has state RUNNING. When it is not playing it has state IDLE. No SUSPEND on my PC.
Your pactl list sinks output shows that sink "323" is in SUSPEND state  (see: pactl list short sinks)

What are your outputs with:
pamixer --get-volume
pactl get-default-sink
pactl list short sinks

Re: No sound over DisplayPort

Hi,

I've checked pavucontrol and I've already tried all possible configurations (even if mine is supposed to be 5.1 Surround Digital Output).
I believe alsamixer is just a "fancy" display of the amixer -c0 I posted.

Concerning sink state either I'm on HDMI or DP, I have the same behavior :
I play something -> state RUNNING
I stop it -> STATE IDLE
I wait few seconds -> STATE SUSPENDED
Except with DP there is no sound.

pamixer --get-volume returns 100

pactl get-default-sink

alsa_output.pci-0000_00_1f.3.hdmi-surround.2

pactl list short sinks

1352	alsa_output.pci-0000_00_1f.3.hdmi-surround.2	PipeWire	s32le 6ch 48000Hz	SUSPENDED

Note : sink number and sink name does not match previous pact list sinks command as I've made some plugging/unplugging between HDMI and DP.
I see a .2 after hdmi-surround in sink name.

Re: No sound over DisplayPort

And your sure that one sink is not inactive?
alsamixer is used to control/deactivate/set volume ect. of the audio hardware in a bash.

For me it looks like this, when I disable on my Displayport output the sink:

Have you tried another DP cable? Maybe it become defect.
Can you set volume on the monitor menü?
