Ubuntu

Should alsa-base.conf have mbp101 model added for snd_hda_intel automatically?

Asked by John McAleely

I recently installed Ubuntu 13.04 on a MacBookPro10,2.

After working around lp #1169984, I found that the internal microphone still did not work.

After some googling, I found this article: http://www.rdoxenham.com/?p=317 where this is noted as a necessary step to properly enable audio on this laptop:

# echo "options snd_hda_intel model=mbp101" >> /etc/modprobe.d/snd_hda_intel.conf

On my machine, I placed the same option into /etc/modprobe.d/alsa-base.conf, mostly because the contents looked like an appropriate place to put it.

Was that the appropriate file to use on Ubuntu? Should some part of the installation/configuration process have done this automatically?

Details of the sound setup on this machine are here: http://askubuntu.com/questions/304455

You can use alsa-base.conf if you like. Keeping configs for the same thing is sensible. You can also make your own file. If do be sure it has a .conf extension but there is no hard and fast rule. If you want to run the command you gave in the question without becoming root, run:

 echo "options snd_hda_intel model=mbp101" | sudo tee -a /etc/modprobe.d/alsa-base.conf

Easy peasy

OK, so that covers whether I've added it to the right file - thanks!

However, should something in the setup have done this for me? As it stands Ubuntu installs with a non-working Microphone on this Laptop. Is that expected?

Been saying it for years. dmidecode picks up makes and models and deb files could be made for those models and installed first time. Sadly it would require a tonne of effort so it is dealt with on an ad-hoc basis using forums and such.
