No sound over pipewire after switching to nouveau driver for nvidia

Hi.

I would like to ask for your help. It's always been a horrible experience for me to fix issues with sound on linux. There are many sound servers and sometimes i'm confused.

I have to switch to nouveau driver for nvidia card because after last system update i had no driver loaded at all. Could not use nvidia so switched to open driver.

I have installed pipewire and pipewire-pulse. But i just don't have sound. Could somebody help me? I'm newbie if it comes to sound over this. Always this was my problem. It is often related to some way of working with it. For an example, we use pulseaudio, but command posted on Archiwiki related to pipewire uses commands that are only available when...we have alsa installed but chapter is realted to pipewire-pulse. The sound on Linux is horror for peiople that does not digg much into it but just want to use sound...

Re: No sound over pipewire after switching to nouveau driver for nvidia

Well, i've been digging and in my opinion my setup is ok. I've purged pipewire, installed clean pulseaudio and the same. I think that the problem is discribed here:

https://download.nvidia.com/XFree86/gpu … pulseaudio

To validate that the ALSA driver is aware of your monitor, check the eld files. Recall that older chipsets (ION and earlier) don’t support ELD reporting, and hence the ELD files will not exist. In this case, ALSA always assumes that all audio features are available.

For example,

$ cat /proc/asound/card1/eld#3.0
monitor_present     1
eld_valid           1
monitor_name        DELL U2410
connection_type     HDMI
eld_version         [0x2] CEA-861D or below
edid_version        [0x3] CEA-861-B, C or D
manufacture_id      0xac10
product_id          0xf016
port_id             0x40000
support_hdcp        0
support_ai          0
audio_sync_delay    0
speakers            [0x1] FL/FR
sad_count           1
sad0_coding_type    [0x1] LPCM
sad0_channels       2
sad0_rates          [0xe0] 44100 48000 88200
sad0_bits           [0xe0000] 16 20 24
For HDMI audio to work, both monitor_present and eld_valid must be 1. Furthermore, there will typically be evidence of at least some supported audio formats.

See Incorrect Reporting of Supported Sample Rates for issues with ELD reporting.

And in my case i'm using nouveau and the present values mentioned above are 0. Also, during boot i see that there is sinformation in dmesg with incorrect ELD...so i can't use nouveau having nvidia, and i can't use nvidia driver having nvidia cards...Suprized.
