Bug Description
I cannot get the microphone input on my Dell Inspiron 630m laptop to work. I'm using latest dapper, and have tried every possible permutation of mixer settings. I either get a quiet hiss or complete silence.
The sound hardware uses the snd_hda_intel module. Here's the relevant lspci output:
$ lspci -vv -s 00:1b.0
0000:00:1b.0 0403: Intel Corporation 82801FB/
Subsystem: Dell: Unknown device 01b5
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
Latency: 0, Cache Line Size: 0x10 (64 bytes)
Interrupt: pin A routed to IRQ 169
Region 0: Memory at dfebc000 (64-bit, non-prefetchable) [size=16K]
Googling for this issue suggests that many other people with this hardware have this problem too, including this cryptic comment:
"""No mic inputs
(updated 20/03/2006)
This is annoying - all of the outputs are doing their thing but not the inputs... Presently, the mic/line jack appears to be as dead as a doornail. I reckon this is again due to the way this chipset can re-task jacks at will, as under windows when you plug a device in it asks you "is this a MIC or a Line-level device?"... Presently chatting with some Alsa peeps to see if they have any ideas..."""

Confirmed, I only get static that stops as soon as I set the PCM output to 0.
