Kacper ,

thank you for your time. I have sound but sometimes after playing a
youtube video music stops playing from totem, etc. Below is what I am
doing and what the "problems" are.

Left speaker doesn't work, controls mixed up on Apple MacBook[Pro] (5,1)

Bug description:
Reporting this bug for another user...

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.

This bug is confirmed by several users, see the additional information attached.
