Alsa module need model=uniwill-m31 to work on my laptop

[Sylvain Defresne]

I just bought a laptop, and had some trouble making sound work. After some reading on the forum and experimentation, I managed to make it work, by passing the model=uniwill-m31 to the snd-hda-intel module. So, maybe the alsa developer may be interested in adding this model to the database so that it will be automatically recognized in next version of the drivers.

First off, look to
http://bugzilla.kernel.org/show_bug.cgi?id=8016
And second one,

I just installed the Beta of Ubuntu 7.10 today, and I still had to manually add the following line to /etc/modprobe.d to get sound :

  options snd-hda-intel model=uniwill-m31

So either, those patch have not been integrated in the kernel used by Ubuntu 7.10, or they are not working.

Hi Sylvain,

The 18 month support period for Edgy Eft 6.10 has reached it's end of life. As a result, we are closing the linux-source-2.6.17 Edgy Eft kernel task. However, Hardy Heron 8.04 was recently released. It would be helpful if you could test the new release and verify if this is still an issue - http://www.ubuntu.com/getubuntu/download . You should be able to test your bug using the LiveCD. If the issue still exists, please add the Hardy kernel "linux" task to the bug report. This can be done by clicking on the "Also affects distribution" link in the Actions area on left hand side of the bug report. Select "Ubuntu" as the Distribution and type in "linux" for the Source Package Name. Thanks.

I tried the Hardy LiveCD and the sound was working without modification, so I guess the bug was corrected. Thank you,

Thanks for the follow up. Glad to know that your issue has been resolved.
