[Bug 59569] snd_hda_intel driver provides only playback on macbook

Fri Sep 8 20:32:43 UTC 2006

Public bug reported:

Binary package hint: linux-image-2.6.15-26-686

This bug has been confirmed on other brands of laptop with the same
chipset but there's nothing in malone about the macbook. It seems the
same driver can be used for a number of different codecs.

The ALSA driver for this card loads and the mixer settings are displayed
properly. Playback with volume control functions and there are options
to select between the different capture sources. Unfortunately all the
capture sources record silence via the built in microphone. I have not
been able to test this with the mini plug microphone input.

An IRC user named crimsun on #ubuntu-laptop said this will be fixed in
the next kernel update for dapper but he didn't know if someone had
alreaady posted a patch. I searched around and couldn't find a patch
either.

Here is the relevant information on the kernel and hardware
