what should I do if directory /etc/alsa-card-profile/mixer/paths/ doesn't exist? if i create one then after the command sudo cp -r /usr/share/alsa-card-profile/mixer/paths/ /etc/alsa-card-profile/mixer/paths/ there are a paths folder inside a path folder, I dont think thats what you meant

what should I do if directory /etc/alsa-card-profile/mixer/paths/ doesn't exist? if i create one then after the command sudo cp -r /usr/share/alsa-card-profile/mixer/paths/ /etc/alsa-card-profile/mixer/paths/ there are a paths folder inside a path folder, I dont think thats what you meant

Yes, the folder should be created, I have fixed the copy command and made some things clearer, thanks for the observation. Can you try again?

This is how the file structure should look like after completing the guide (and replacing with your card information):

        Ports:
                analog-output-speaker: Speakers (type: Speaker, priority: 10000, availability group: Legacy 3, not available)
                analog-output-headphones: Headphones (type: Headphones, priority: 9900, availability group: Legacy 4, available)
        Active Port: analog-output-headphones
        Formats:
                pcm

so I assume that the mixer path im looking for is analog-output-speaker.

I've created the folder and copied, after running tree /etc/alsa-card-profile/ i get 

/etc/alsa-card-profile/

3 directories, 45 files

I've edited the file analog-output-speaker.conf and changed the description-key to something else. but after restarting pipewire and listing the sinks again i still get the same message, however if i do it on the same file in /usr/share/alsa-card-profile/mixer/paths/ I do see a change, it's like pipewire doesn't care about the folder in /etc

Shmerlard commented 2 months ago

also since I'm using debian the only package I couldn't find is alsa-card-profiles but the files were already there so I don't know if it matters.

luisbocanegra commented 2 months ago

Fount this in PipeWire documentation

For ACP, PipeWire looks for the profile configuration files under

- ~/.config/alsa-card-profile
- /etc/alsa-card-profile
- /usr/share/alsa-card-profile/mixer`. 

The `path` and `profile-set` files are in subdirectories `paths` and `profile-sets` of these directories.
It is possible to override individual files locally by putting a modified copy into the ACP directories under `~/.config` or `/etc`.

So that means paths and profile-sets should be read from /etc/alsa-card-profile instead of /etc/alsa-card-profile/mixer can you try that or putting it in ~/.config?

I think your pipewire version is just too old and may not support any of that. If that's the case you can still use /usr/share/alsa-card-profile/mixer to continue the tutorial but that folder will be overwritten by updates

On debian those files are provided by pipewire-bin

Shmerlard commented 2 months ago

so after trying the with putting it in ~/.config and in /etc/alsa-card-profile it didnt work. so I checked and apparently yes the version of my pipe wire was outdated because of debian 12 (it was version 0.3.65), so i added the testing repository of debian and updated pipewire to 1.0.3. after editing the file in ~/.config/alsa-profile-card/paths it worked! i can see a different output for pactl list sinks. so I will continue like this and see what happens although after everything I changed in the system for the past 2 days I feel like changing to arch.

Shmerlard commented 2 months ago

Ok, so 2 more things. 1) after updating the version i tried again with putting it in /etc/alsa-card-profile/ but it didn't work, but with ~/.config it worked,

2) ive edited the file by commenting the lines and changing from no to unknown as described. and when I changed the output to headphones the speaker was muted, but all I had to do was changing it in alsamixer and now it works. so maybe you would want to add these things to the guide, meanwhile lets see if any more problems occur.

Glad you were able to get it working.

Thanks, will try these two locations and add it to the guide probably this weekend

This is with or without the firmware patch?

Shmerlard commented 2 months ago

that was without the firmware patch, but yesterday I installed arch (wanted to try kde6) and today it worked flawlessly and now everything is working great. I have another audio device which is my screen via hdmi so I'll try to add this too. you don't know how I appreciate your help man! Many many thanks

Shmerlard commented 2 months ago

Okay the HDMI now works! for me the HDMI was on device 3, so in /etc/alsa-card-profile/mixer/profile-sets/split-ports-profile.conf I added the following:

[Mapping hdmi-output-0]
description = HDMI
device-strings = hw:%f,3
paths-output = hdmi-output-0
channel-map = left,right
direction = output

and replaced 

[Profile output:analog-stereo-headphones+output:analog-stereo-speaker+input:analog-stereo-input]
description = Analog Stereo Duplex
output-mappings = analog-stereo-headphones analog-stereo-speaker
input-mappings = analog-stereo-input
priority = 80

with:

[Profile output:analog-stereo-headphones+output:analog-stereo-speaker+output:hdmi-output-0+input:analog-stereo-input]
description = Analog Stereo Duplex
output-mappings = analog-stereo-headphones analog-stereo-speaker hdmi-output-0
input-mappings = analog-stereo-input
priority = 80

after rebooting an HDMI sink appeared but no sound came out of it so in alsamixer just unmute the S/PDIF channels and store the results. and it should work

Nice that you were able to extend even further 🎉

Yeah, this muting started happening for me too after some update, I am tracking it here for when I have time to investigate it. In the meantime will add a note about alsamixer as you mentioned earlier.

you don't know how I appreciate your help man! Many many thanks

You're welcome! If you are able to, consider making a small donation (if you can't is also fine) ❤️

luisbocanegra commented 2 months ago

Hi again, can you try https://github.com/luisbocanegra/linux-guide-split-audio-ports/issues/13#issuecomment-2053710320 for the muting problem?
