Yeah, I came across this on my desktop workstation. With that I could not get the mic to work either, but I found in alsamixer that I could select "mic2". Once I did that, I could hear sound from the mic through the speakers *and* record. On the Thinkpad, if I switch to mic2 in alsamixer I can no longer hear sound from the mic through the speakers, nor do the recording apps capture any sound :-( Is there a diagnostic tool that can reveal more information? BTW, in the Gnome Sound Recorder, the "Record from input:" drop down menu contains 45 (!) entries. There are 8 unique values in the list (e.g. "Line-in" "CD" "Microphone" ...) but the are repeated several times. Odd in itself. I had someone mention KMix so I've given that a go as well. KMix reveals many more options and I must have worked through every possible combination - no joy :-( I would be good if there was some kind of absolute identity for the microphone and some way of directing the recording programs to it - at the moment the recording programs look at /dev/dsp and then a miracle occurs ... or in this case, does not. Thanks for all the suggestions so far. -- Make the most of your skills - with OpenSkills http://www.openskills.org/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
