#1

The ALC256 does not have a mixer nid at 0x0b, and there's no
loopback path (the output pins are directly connected to the DACs).

This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)"
error (and as a result, problems with amixer/alsamixer).

If there's pcbeep functionality, it certainly isn't controlled by setting an
amp on 0x0b, so disable beep functionality (at least for now).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-vivid' to 'verification-done-vivid'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
