Macbook users experiencing sound problems with heir speakers in Ubuntu 11.04 may benefit from the following ‘fix’. 

Adwait, of blog ‘thepirado’, wrote of a fix he found via the Ubuntu IRC channel.

Fix low volume sound on a Macbook with Ubuntu 11.04

You need to add a new line to a system module configuration file.

As poking around with system modules can be risky, make sure you only edit/enter the commands stated below.

Open a terminal (or ALT+f2) and enter the following command:

  • gksu gedit /etc/modprobe.d/alsa-base.conf

In the text file that opens up add: –

  • options snd-hda-intel model=mbp55

to the bottom of the document. Hit save and close. Reboot Ubuntu and, providing this was the issue afflicting you, your sound should return to normal.

Adwait was also experiencing issues with the speaker’s LED. He suggests adding: –

  • amixer set IEC958 off

to the file above to switch it off.
