Ok. So far so good. I've just seen the same errors above, while Googling on that Mitac (unknown device) 8227, that shows up on lspci for your soundcard. Will you run the command below. grep ^Codec /proc/asound/card?/codec* You should see 2 codecs. ALC883 (The correct one for the snd-hda-intel module), and also ALC268, which appears to be something to do with this Mitac 8227 component on the card. The fix on the Ubuntu forum (french), was to patch the alsa driver, but the instructions are for Ubuntu Hardy Heron, and that has alsa driver 1.0.16, which is the same as the installed driver on F9, before you upgraded it. Link to the frech Ubuntu forum below. http://doc.ubuntu-fr.org/audio_intel_hda Now it may be that the model=medion option is the wrong one, and I see from the very sparce specs for your machine on the Medion site, that your card provides 6 channels plus digital out. It's possible that the alsa development folks have already applied a patch on the 1.0.18a driver that you now have, but it's just the model option which is wrong. Would you try the following one. options snd-hda-intel model=3stack-6ch-dig The same forum page for the fix above shows that as an option for the Medion MD96367, where both ALC883, and ALC268 codecs are detected. It's not your model, but worth a try. If that produces no changes in Alsamixer, we may have to ask the Alsa dev folks. It's possible that the 1.0.18a driver has had the necessary patch applied since 1.0.18a was released, and there are nightly snapshots of the driver available, which include the latest patches. Anyway. Try the above model option first. If you want to try other model options, you will find the ones for ALC883 codec in the folder that was produced when you unpacked the driver, under, alsa-kernel > Documentation > Alsa-Configuration.txt . Just scroll down to snd-hda-intel, and a bit firther down for the ALC883 codec.
