My VT1802 chip has a beep-generating node:

But I'm missing the:

entries that I think I need to manage this widget from alsamixer. For example, sambrian posts codec output for a CX20561 chip which has [1]:

I can patch with something like this:

...

...

but that doesn't add the beep controls. Looking at patch_analog.c, patch_conexant.c, and patch_realtek.c for inspiration, I expect we'll need an HDA_CODEC_MUTE_BEEP(_MONO) entry, and possibly an HDA_CODEC_VOLUME(_MONO) entry, but I'm not sure if these should be mono or not, or if they should be inputs (following patch_realtek.c) or outputs (following patch_analog.c and patch_conexant.c). I've filled out Via's datasheet-request form [2], but I don't know how likely that is to be accepted.

According to your output, the node 0x22 has:

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]

so this should mono and output.

Other codecs may have different controls because rather controlling in the input of the mixer widget or such.

Why beep generator cannot automically found by auto parser ?

It can be, but it's not always connected to the right I/O in the topology, so left as codec-specific for now.

My codec has a beep-generating node:

This is pretty much what patch_conexant.c's cx_auto_parse_beep() does, so I've just shifted that code over here to handle beeps in VIA codecs. It works on my VT1802, but I don't have any other VIA codecs around to check that it works on all of the VIA codecs (Takashi pointed out that they can be buggy [1]). Do I need to shift the auto_parse_beep() check into the VT1802-specific portion of patch_vt2002P(), or can I leave it here in the generic via_parse_auto_config()? Alternatively, we could wedge it into via_new_spec(), which would give the per-codec patches time to clear spec->gen.beep_nid for broken codecs before via_parse_auto_config() calls snd_hda_gen_parse_auto_config() which consumes beep_nid.

I guess it's OK as is. Not all VIA codecs seem to have the beep widget, and the codecs with the beep widget have all the same functionality (digital beep with the output amp).

Care to brush up your patch as a formal form to be merged to upstream? There are a few conflicts with the latest sound.git tree code, but I can manage to resolve them.

Later on, we can move the common code to the generic parser (with yet some behavior flag), but it can be done by another patch.

Done. The only change since v1 is rebasing from v3.19 to the current sound.git master, resolving some trivial conflicts with 688b12cc (ALSA: hda - Use the new power control for VIA codecs, 2015-03-17). If you feel inclined to make further edits to my commit message, you have my permission.

Works for me.

OK, I applied the patch with a slight modification.
