A while ago my external microphone stopped working on my laptop. When I first received the laptop the external mic wouldn't work - it was fixed by reinstalling the system76 driver. Hoping the same would work again, but instead, after rebooting, the package manager showed an error - alsa-source (Installed and latest versions shown as 1.0.15rc3-ldd1). At the time the system76 driver was 2.2.0.
So, I marked alsa-source for complete removal - rebooted without errors. I updated all packages, including syst76 driver and rebooted again for the fun of it. Then re-ran the syst76 driver and rebooted. Then I get the alsa-source error again.
Volume control shows 'HDA Intel (Alsa mixer)'. The playback tab shows Master and PCM but the only Capture device is 'capture'. If I use volume control - File- change device to go to 'Generic 14f1 ID 5054 (OSS Mixer)', the playback tab shows 'Volume' and 'In-gain', but no capture tab is displayed.
I'm testing the mic with Sound-recorder 2.14.2 - record from input 'capture'.
Celeron M CPU 410@1
Driver is shown as v2.2.1 in system76 driver installer- about
(yet, looking the changelog in /opt/system76/system76-driver/src, it shows 2.2.2.)
Ubuntu 6.06LTS (yes, I know its not the latest LTS)
incidenly, the repository shows alsa-source of 1.0.10-4Ubuntu4)
