Hi,

My MacBookPro7,1 (nVidia MCP89) has a problem with the sound on its internal speakers.

The 'Front Speaker' works properly, but is quite "thin" and quiet. The 'Surround Speaker' completes the volume level properly, but only the right channel works. Switching 'Surround Speaker' on/off for both left/right, or manipulating the 'Surround Speaker Playback Volume' only has an effect on the right channel, the left stays silent.

It'd be nice if someone could provide me a patch or some guidance for patch_cirrus.c so we can fix this.

Thanks,

Mourad

PS: here are the relevant mixer controls. (is there a reason why the surround switch and volume are separated?)
