I get a noticeable amount of oscillating noise from the headphones now, using the patch against ALSA 1.0.19, and following the instructions on the wiki for using PulseAudio with 6 channel sound. The oscillating noise goes away when I mute the HP channel. However, when I mute it, I can hear a steady tone. If I slide the volume sliders up and down for the HP channel, the pitch will change (randomly, not directly or inversely).
Additionally, the internal mic does not seem to work for me. Whenever I open Volume Control and go to the recording tab, the channel is always shown with a muted mic button. I unmute it and try to record with GNOME Sound Recorder, but it doesn't record anything. -- Left speaker doesn't work, controls mixed up on Apple MacBook[Pro] (5,1) https://bugs.launchpad.net/bugs/337314 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support.

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.
