I have a strange issue. My speakers are plugged into the rear (motherboard) audio out (yes I’ve checked, it’s in green), and my headset is plugged into the front case audio out. The speakers work when the headset isn’t plugged in, and the headset works when speakers are plugged in, but when they are both in, speakers doesn’t work in Audio panel (selecting Line Out when mic plugged into front of case).
Ditto for the mic
Headset mic works when rear mic isn’t plugged in
Also, SOMETIMES the front mic will work for some reason when rear mic is plugged in
^Like if I switched it intentionally in the audio panel
Additionally pulseaudio -k restarts normally, bu still has the same issue.
Speakers work normally when tested. After plugging in headset, they no longer work. Audio panel → manually set to speakers does nothing aside for mute all sound. Speaker volume is not muted in pavucontrol and audio panel.
Not sure where to go from here
How can I restore proper working order of both my speakers and motherboard audio so that I can choose which one I want instead of having to manually unplug the headset to get the speaker to work?
Your description suggests you have Auto-Mute Mode enabled in ALSA
Laptop users may want this setting enabled so built-in speakers are muted when headphones are plugged in.
But on a desktop system, a user may not want audio to speakers muted if headphones are plugged in
Disabling Auto-Mute Mode allows speakers to be unmuted when headphones are plugged in
The user has full control of both audio devices
OP appeared to be a request to use speakers all of the time and not headphones
So my response suggested muting Headphones in ALSA
(most onboard audio codecs are like your system and have only one analog audio subdevice shared between speakers and headphones, but a few have have 2 subdevices)
KDE audio controls relate to Pulseaudio and cannot control ALSA audio devices
