Hi ALSA users.
I'd like to utilise the jacks of my ALC1150 HDA device as separate
stereo outputs.
I have a motherboard with onboard audio powered by the ALC1150 chipset.
The board has 5 stereo jacks (Green, Black, Orange, Pink, Blue), which
by default are assigned:
- 6 channel/5.1 out: Green (Pin 0x14), Black (0x15), Orange (0x16)
- 4 channel in: Pink (0x18), Blue (0x1a)
I've used hda-jack-retask to retask the input jacks as outputs.
`demsg` shows that snd_hda_codec_realtek is correctly seeing 5 outputs:
autoconfig for ALC1150: line_outs=5 (0x15/0x16/0x18/0x1a/0x14) type:line
speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
hp_outs=0 (0x0/0x0/0x0/0x0/0x0)
mono: mono_out=0x0
inputs:
If I try and use speaker-test to test all 10 channels, it fails:
$ speaker-test -D hw:0,0 -c 10
...
Unable to set hw params for playback: Invalid argument
Setting of hwparams failed: Invalid argument
Yet, 8 channels works:
$ speaker-test -D hw:0,0 -c 10
0 - Front Left
4 - Front Center
1 - Front Right
7 - Side Right
3 - Rear Right
2 - Rear Left
6 - Side Left
5 - LFE
To verify that it wasn't a problem with the two retasked line in
jacks, I reconfigured the device so that only the Pink and Blue jacks
were present:
