suggestion: Full file path in udev configuration

[mh0rst]

Hi, first of all thank you for compiling the invaluable guide. I replicated it on a Ubuntu 23.10 system with a Realtek S1220A sound chip (from ASUS ProArt X670E Creator motherboard).

One deviation I had to make from your guide was to specify the full path to the split-ports-profile.conf in the udev configuration, just specifying the file name didn't work - it seems like at least my version of wireplumber (0.4.14-4ubuntu1) does not search in /etc/alsa-card-profile/mixer/profile-sets by default:

wireplumber[2946]: profile-set '/usr/share/alsa-card-profile/mixer/profile-sets/split-ports-profile.conf' can't be accessed: Datei oder Verzeichnis nicht gefunden

With this udev config, everything is recognized and the split ports are working:

SUBSYSTEM!="sound", GOTO="pipewire_end"
ACTION!="change", GOTO="pipewire_end"
KERNEL!="card*", GOTO="pipewire_end"

SUBSYSTEMS=="pci", ATTRS{vendor}=="0x1022", ATTRS{device}=="0x15e3", \
ENV{ACP_PROFILE_SET}="/etc/alsa-card-profile/mixer/profile-sets/split-ports-profile.conf"

LABEL="pipewire_end"

Hi, sorry for the long wait. Can you try setting it back to just the file name and after rebooting/restarting pipewire (systemctl restart --user pipewire pipewire-pulse pipewire.socket wireplumber) run

pactl list sinks | grep -E 'Name|Desc|State|Port|device.profile-set'

I want to add a note to the guide but need a way to check if the profile is being used or not.

In my case without absolute path the profile is applied properly and I see this:

State: IDLE
Name: alsa_output.pci-0000_00_1f.3.analog-stereo-headphones
Description: Built-in Audio Headphones
        device.profile-set = "split-ports-profile.conf"
Ports:
Active Port: analog-output-headphones
State: SUSPENDED
Name: alsa_output.pci-0000_00_1f.3.analog-stereo-speaker.2
Description: Built-in Audio Speakers
        device.profile-set = "split-ports-profile.conf"
Ports:
Active Port: analog-output-speaker-split

Edit: updated the output to reflect non absolute path working on my machine

I tried your suggestion and configured just the file name, this would not work, the separate headphone port would not appear:

$ pactl list sinks | grep -E 'Name|Desc|State|Port|device.profile-set'
    Name: alsa_output.pci-0000_6d_00.6.analog-stereo
        device.profile-set = "split-ports-profile.conf"
    Ports:
    Aktiver Port: analog-output-headphones
    Name: alsa_output.usb-Generic_Blue_Microphones_2052BAB0D0E8-00.analog-stereo
    Ports:
    Aktiver Port: analog-output-speaker
    Name: alsa_output.pci-0000_03_00.1.hdmi-stereo-extra4
    Ports:
        hdmi-output-4: HDMI / DisplayPort 5 (Typ: HDMI, Priorität: 5500, Verfügbarkeitsgruppe: Legacy 5, verfügbar)
    Aktiver Port: hdmi-output-4

With full absolute path, the splitted headphone port is back:

$ pactl list sinks | grep -E 'Name|Desc|State|Port|device.profile-set'
    Name: alsa_output.usb-Generic_Blue_Microphones_2052BAB0D0E8-00.analog-stereo
    Ports:
    Aktiver Port: analog-output-speaker
    Name: alsa_output.pci-0000_03_00.1.hdmi-stereo-extra4
    Ports:
        hdmi-output-4: HDMI / DisplayPort 5 (Typ: HDMI, Priorität: 5500, Verfügbarkeitsgruppe: Legacy 5, verfügbar)
    Aktiver Port: hdmi-output-4
    Name: alsa_output.pci-0000_6d_00.6.analog-stereo-headphones
        device.profile-set = "/etc/alsa-card-profile/mixer/profile-sets/split-ports-profile.conf"
    Ports:
    Aktiver Port: analog-output-headphones
    Name: alsa_output.pci-0000_6d_00.6.analog-stereo-speaker
        device.profile-set = "/etc/alsa-card-profile/mixer/profile-sets/split-ports-profile.conf"
    Ports:
    Aktiver Port: analog-output-speaker

I don't know if it is related to this issue: I also need to unmute my headphone in alsamixer on each boot, I know I could automate this unmuting but I'd rather configure alsa correctly. Saving the unmuted state with alsactl did not work.

Thanks for verifying, will add the note to the readme about this

I have this too but haven't had the time to investigate it.

Updated the guide to use full path and created a new issue for the muting problem. Thanks again for your feedback.

[luisbocanegra]

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

[mh0rst]

Hi, sorry for the delay, your follow-up got lost in between lots of work. I just finished the upgrade from Ubuntu 23.10 to 24.04 LTS and wanted to try your suggestion, but the upgrade somehow fixed the muting issue. Your solution without editing analog-output-headphones.conf works perfectly for me now :)
