ALSA: hda/via - Add beep controls to VIA codecs
My codec has a beep-generating node:
$ cat /proc/asound/card1/codec#0
Codec: VIA VT1802
...
Vendor Id: 0x11068446
Subsystem Id: 0x15587410
Revision Id: 0x100000
...
Node 0x22 [Beep Generator Widget] wcaps 0x70040c: Mono Amp-Out
Amp-Out caps: ofs=0x0a, nsteps=0x12, stepsize=0x05, mute=1
Amp-Out vals: [0x0a]
Power states: D0 D1 D2 D3
Power: setting=D0, actual=D0
...
But I was missing the:
Control: name=...
entries that I need to manage this widget from alsamixer. With this
patch (based on the similar Mono Amp-Out handling in
patch_conexant.c), I get a new:
input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/sound/card1/hdaudioC1D0/input15
entry in dmesg and controls to manage that beep:
$ cat /proc/asound/card1/codec#0 | grep -A5 Beep
Node 0x22 [Beep Generator Widget] wcaps 0x70040c: Mono Amp-Out
Control: name="Beep Playback Volume", index=0, device=0
ControlAmp: chs=1, dir=Out, idx=0, ofs=0
Control: name="Beep Playback Switch", index=0, device=0
ControlAmp: chs=1, dir=Out, idx=0, ofs=0
Amp-Out caps: ofs=0x0a, nsteps=0x12, stepsize=0x05, mute=1
Amp-Out vals: [0x12]
Power states: D0 D1 D2 D3
Power: setting=D0, actual=D0
