I've been helping GN out on the user list, to get his sound working. The sound is now working, but only by using the options line below. options snd-hda-intel probe_mask=1. I see on the changelog for 1.0.18 > 1.0.18a that Takashi added a quirk for a Medion MD96630 as below.

<quote> - ALSA: hda - Add a quirk for MEDION MD96630 Use model=lenovo-ms7195-dig for MEDION MD96630 laptop (17c0:4085) with ALC888 codec.

Some details of his machine, OS, and other output below.

A bit of info from Graeme (aka GN), after asking him to try probe_mask=1.

<quote> I tried the different probe-mask=?. Probe-mask=1 works OK but not the others. model=lenovo-ms7195-dig doesn't work. Kmix shows varying channels depending on the 'model' or 'probe-mask' used. probe-mask=1 gives the most channels. alsamixer now loads up OK but still no sound. Shows as ALC883 with 'probe-mask=1' Starting Amarok elicits the xine error dialogue window with "xine was unable to initialize any audio drivers"

UPDATE:

With 'probe-mask=1 and using Rhythmbox I can get sound out of the speakers and the front headphone jack. Volume not very high out of the speakers but is good from the headphones. Too much system activity or keyboard activity (I'm writing this listening to Tchaikovsky and I can hear interruptions from the keyboard at times) seems to interfere with the audio stream. Also there is a lot of noise from the CD drive coming through the earphones. Don't know how that is happening. Pulseaudio Vol Cntl can be used as can the panel Vol. Cntl. and also alsamixer. <end quote>

The last things I asked him to try, were to disable Pulseaudio, by removing the package alsa-plugins-pulseaudio, and to try the latest snapshot for the alsa driver.

Disabling pulseaudio has resulted in good sound levels from the speakers, but as he is away for a few days, he hasn't yet tried the latest snapshot of the alsa driver.

A few extra details. Without a model option all snd modules were loaded, but no card was detected. Using the option model=medion, resulted in the card being detected, but problems with alsamixer as below. model=mitac gives same results as below.

<quote from Graeme's reply on user list> [graeme@flintstone ~]$ amixer ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more amixer: Mixer default load error: Invalid argument [graeme@flintstone ~]$ alsamixer ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more

alsamixer: function snd_mixer_load failed: Invalid argument <end quote>

Then I searched through the changelog, found the bug report about the codec conflicts, and suggested probe_mask=1, which has got the sound working.

I think I've gone about as far as I can now, which is why I'm posting this to the devel list.

Nigel.
