- Build the latest driver with your pingconfig patch.
Patch, which adds an "intel-imac-20" pinconfig attached.
- Unload the driver module. - Remove /etc/asound.state (or whatever alsactl stores -- the path is depending on distro) - Load the module again; at this state, mixers are muted - Get the first codec dump here once
initial-codec attached.
- Unmute the playbacks as usual. Check playback.
Playback works.
- Turn on only "Capture Switch". Don't adjust "Capture Volume" and "Mux Capture Volume" if they are zero. Test recording once here. Get codec dump again.
Recording doesn't work. Codec diff: Node 0x02 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out Amp-Out caps: N/A - Amp-Out vals: [0x7f 0x7f] + Amp-Out vals: [0xff 0xff] Power: 0x0 Node 0x03 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out Amp-Out caps: N/A - Amp-Out vals: [0x7f 0x7f] + Amp-Out vals: [0xff 0xff] Power: 0x0 Node 0x04 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out Amp-Out caps: N/A - Amp-Out vals: [0x7f 0x7f] + Amp-Out vals: [0xff 0xff] Power: 0x0 Node 0x05 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out Amp-Out caps: N/A - Amp-Out vals: [0x7f 0x7f] + Amp-Out vals: [0xff 0xff] Power: 0x0
- If not working, try resetting the input source. Test recording. Get codec dump.
Reseting the input source doesn't result a difference in the codec info and recording still doesn't work.
- Raise "Capture Volume". Test recording, get codec dump.
After this recording works! Woho! :-)
Node 0x17 [Audio Selector] wcaps 0x300903: Stereo Amp-In
Amp-In caps: N/A
- Amp-In vals: [0x0e 0x0e]
+ Amp-In vals: [0x00 0x00]
Connection: 1
0x12
- Raise "Mux Capture Volume". Test recording, get codec dump.
For the sake of the test I have also umuted and increased Mux, which
results the following diff and a non-working recording
Node 0x12 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
Amp-Out caps: ofs=0x00, nsteps=0x04, stepsize=0x27, mute=0
- Amp-Out vals: [0x04 0x04]
+ Amp-Out vals: [0x00 0x00]
Connection: 7
0x0e 0x15 0x0f 0x0b* 0x0c 0x0d 0x0a
Regards.
