I have a Dell Inspiron 4150 that has the Cirrus Logic CS4205 rev 3, I can record using the mic input using alsa rc5, I think I could using rc3 as well. I just tested it to make sure and it works for me although I have to be careful to turn the pcm output or ardour outputs down while recording or I get a feedback loop. The CS4205 has been good so far for me, I can get pretty low latency with a patched kernel. Only problem I had was that if I came back from a suspend, I could get no sound out of alsa until I moved the pcm control in the mixer, but that might of been fixed in rc5. > One more thing is that CS4205 is a full-blown dsp so while it is > compatible with the intel8x0 standard, it in addition has some nice > features to offer, such as hw multi-open as well as SPDIF and other > gizmos.
