Hello;
I have an MSI CN700T ITX motherboard with a VIA 8237 SouthBridge and a VIA 1618 codec.
Using aplay and speakertest, 2 channel sound works well, but 6ch sound with the ever popular chan-id.wav* produces no output.
However, neither aplay nor speakertest *fail* when attempting to write to the other channels so they evidently exist, but may be muted.
I went to the trouble of installing windows and the VIA Vinyl driver for same and after I used the via configuration app to set the mic and line inputs to be C/LFE and Rr outs, I received the expected output.
Is 1618 6ch expected to work with ALSA 1.0.13?
based on looking at ac97_codec.c: static const struct ac97_codec_id snd_ac97_codec_ids ,
it seems to be stubbed out instead of fully implemented:
{ 0x56494182, 0xffffffff, "VIA1618", NULL, NULL },
My suspicion is that I need to create the following items (hx3rd from the vt1616 versions):
static const struct snd_kcontrol_new snd_ac97_controls_vt1618
static int patch_vt1618_specific(struct snd_ac97 * ac97)
static struct snd_ac97_build_ops patch_vt1618_ops
int patch_vt1618(struct snd_ac97 * ac97)
Am I correct in my assumptions? If so, what do these 2 arrays and 2 functions actually do?
Tnx!
