Ubuntu – No sound with HDA Intel PCH

12.10alsasound

I don't manage to get sound working on my Ubuntu 12.10. The output of my alsa-info.sh is located here.

I would appreciate any help to fix this problem!

Best Answer

For what it's worth, I've just resolved a no-sound problem on my HDA Intel PCH card: I ran 'alsamixer' in a terminal and unmuted the 'Line' column (with the M key).

Other info:

  • I also made sure to unmute the Master, Headphone, Front, Surround, Center and LFE columns, but it's only when I unmuted Line that sound got out.
  • The 'Chip' line in alsamixer says 'Realtek ALC887-VD'.
  • The sound software never complained about the sound device.
  • My system is Ubuntu 12.04. The speakers are connected to the green connector at the back of the PC.
  • I tested the speakers with another computer.
