Bug Description

On the new Macbook Pro 15 Haswell/Retina 11.1 the speakers do not work in Ubuntu 13.10.

I tried adding "options snd_hda_intel model=mbp101" (and mbp111) to alsa-base.conf but this does not work.

Reinstalling alsa-base and pulseaudio together with sudo alsa force-reload also does not work. Headset does work.

Upstream seems to be working on the issue:

Thank you very much. Unfortunately it does not work for me. Do I still need the also-base settings?

Just as update: the workaround seems to work only for the version with the integrated graphics (see I have the hybrid model running the open source driver (Gallium 0.4 on NVE7).
