=============== [ Upstream commit 7d1b6e29327428993ba568bdd8c66734070f45e0 ] 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).
