After performing more tests with the various "models" I noticed that my default mixer values had changed. After inspecting my alsa-info output from each model= configuration, I realized that I ran my initial apport- collect with model=hp-dv5. I've re-run apport with no module parameters which seems to be most correct. In both cases the headset was plugged in.
The diff on my original apport vs above update for the Mixer and Codec for my STAC 92HD71B71 is below, sorry for the multiple posts, that's just how apport decided to do it. With dv-hp5 the card continuously appears to reset, resulting in a "pop" from the speaker, a mute-unmute cycle and whatever is playing stops, every 30 seconds or so. So I believe no option is correct for my hardware. The hp-hdx option takes away the subwoofer. I have attached an alsa-info.sh script output too, also attached to the upstream bug. $ diff Card0.Amixer.values.txt (updated_auto) Card0.Amixer.values.txt(original_hp-dv5) 51c51 < Mono: Playback 0 [0%] [-18.00dB] [on] --- > Mono: Playback 1 [33%] [-12.00dB] [off] 74,75c74,75 < Front Left: Capture 0 [0%] [0.00dB] < Front Right: Capture 0 [0%] [0.00dB] \ No newline at end of file --- > Front Left: Capture 3 [100%] [30.00dB] > Front Right: Capture 3 [100%] [30.00dB] \ No newline at end of file $ diff Card0.Codecs.codec.0.txt(updated_auto) Card0.Codecs.codec.0.txt (original_hp-dv5) 158c158 < Amp-Out vals: [0x00 0x00] --- > Amp-Out vals: [0x03 0x03] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776599 Title: Headphone Out, Front - Plugging in (and out) not recognized -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
