external mic not working on Dell XPS M1530, Ubuntu 8.04
I cannot for the life of me get the external mic working on my Dell XPS M1530 laptop, running Ubuntu 8.04, 2.6.24-25-generic kernel. The internal mic works fine. To try to get the external mic working, I have configured alsamixer to: Digital Input Source = Analog Inputs, Input Source = Front Mic (plus many other combinations). All of the relevant sliders are turned up. I tried adding the line 'options snd-hda-intel model=dell-3stack' (and other models) to /etc/modprobe.d/alsa-base, and rebooting. Other relevant info:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]
Subdevice #0: subdevice #0
$ cat /proc/asound/card0/codec#* | grep Codec
Codec: SigmaTel STAC9228
Thanks in advance for any help you can provide.
