How to get sound on macbook pro 4,1
- by Thomas
I have just installed Xubuntu 12.04.2. My soundcard is detected:
thomas@thomas-pc:~$ sudo aplay -l

card 0: Intel [HDA Intel], device 0: ALC889A Analog [ALC889A Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: ALC889A Digital [ALC889A Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
Everything is put to max in alsamixer and nothing is muted (all the sliders are on OO. My speakers do not work, but when I plug in a headphone I hear it very soft. When I connect my stereo and put the sound VERY loud (3-blocks-of-complaining-neighbours loud) I hear it on a normal level but crackling.
I added
options snd-hda-intel model=mbp5
amixer set IEC958 off
to at the end of /etc/modprobe.d/alsa-base.conf.
When it's still not working I tried everything here: https://help.ubuntu.com/community/SoundTroubleshooting

2 and 3: Doesn't seem an permission issue, the sound is very far away (See opening paragraph).

7 I guess it's supported. Linux mint and Xubuntu 13.04 had no trouble with sounds. Everything worked out of the box
Thanks in advance
