[pulseaudio-discuss] How to remove a sink port

[coolix]

Hello,

I've been able to fix something that has been driving me crazy for days and
wanted to share it with you.

I've a audio device that expose 2 different ports in Pulseaudio, Speaker
and Headphone :

      ports:
                analog-output-speaker: Speakers (priority 10000, latency
offset 0 usec, available: unknown)
                        properties:
                                device.icon_name = "audio-speakers"
                analog-output-headphones: Headphones (priority 9900,
latency offset 0 usec, available: unknown)
                        properties:
                                device.icon_name = "audio-headphones"
        active port: <analog-output-headphones>

Unfortunately, this audio device itself does not have a Speaker 3.5mm jack,
but only a Headphone 3.5mm jack.

Hence the default priority being higher for the Speaker port, a new user
connected to this workstation will always miss sound and need to change the
active port to be the Headphones manually.

Following is how I fixed this problem.
It's probably not the best way to do things, but my knowledge is limited in
this subject, and it just works !
I would love to receive some feedback from the experts though.

First, I've created a udev rule to match my audio device and use a
user-defined pulseaudio profile

SUBSYSTEM!="sound", GOTO="pulseaudio_end"
ACTION!="change", GOTO="pulseaudio_end"
KERNEL!="card*", GOTO="pulseaudio_end"
ATTRS{vendor}=="0x6549", ATTRS{device}=="0x2200",
ENV{PULSE_PROFILE_SET}="teradici.conf"
LABEL="pulseaudio_end"

Then, I created this user-defined profile, *teradici.conf*, by copying
*/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf
*and removing *analog-output-speaker* from the *paths-output*.

--- default.conf 2020-11-23 17:33:37.000000000 +0100
+++ teradici.conf 2023-04-12 09:01:03.345338558 +0200

After a reboot, this audio device no longer exposes the "missing" Speaker
port and the Headphones port is always selected.

Cheers,
