A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2198> ====================================================================== Reported By: enlighter Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 2198 Category: PCI - hda-intel Reproducibility: always Severity: major Priority: normal Status: assigned Distribution: Gentoo Linux Kernel Version: 2.6.16.16 ====================================================================== Date Submitted: 06-09-2006 12:09 CEST Last Modified: 07-05-2006 15:21 CEST ====================================================================== Summary: No sound out of the built in speakers, but from headphones on a Apple MacBook Pro Description: Hi, this error occours on all macbook pros! (see www.mactel-linux.org). Sound comes only out of the headphones or out of line-out, but the internal speakers keep mute. I cannot unmute them using the mixer (alsamixer, kmix). I also tried a rc version of linux-2.6.17 with the same result. I also tried to load the snd-hda-intel module with "model=laptop" and "model=laptop-eapd". ====================================================================== ---------------------------------------------------------------------- Gendo - 07-05-06 04:18 ---------------------------------------------------------------------- Tiwai. From some testing and some research I have found that the patch works for 17 inch macbook pro, regular macbook, and mac mini. The patch does not however work for the 15 inch macbook pro, and the iMac. There seems to be some sort of difference with the GPIO stuff between the models. This can be seen by some behavior in Windows with disabling the internal speaker. I tried making some changes to patch_sigmatel.c but did not really have any success, I noticed changing the pin definitions altered some of the behavior but I could never get the speaker to make any noise. Is there any function call that could tell the device to set all inputs and outputs on the device as output? If you need any other information please let me know. ---------------------------------------------------------------------- tiwai - 07-05-06 15:21 ---------------------------------------------------------------------- The input and output pins widgets are taken from the BIOS. So, one possibility is that BIOS doesn't initialize properly (although I doubt it since the headphone works). Anyway, upload /proc/asound/card0/codec#* files.
