When recording from a headset microphone, sound quality is really bad: low volume and quite some noise / distortion. I have my microphone mixers maxed out, 'Mic boost' is on, 'Mic as Center/LFE' is off. I've fiddled with all the other options, but they don't seem to affect the quality. I do my recording with: arecord -D hw:1,0 -d 4 test.wav Under Windows, sound quality is a lot better with the same setup. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0001192 Microphone doesn't work in record and/o... ====================================================================== ---------------------------------------------------------------------- tiwai - 11-18-04 20:22 ---------------------------------------------------------------------- When you can't change the values via amixer properly, they are read-only values. Changing the driver won't help then. You can forget the patch. ---------------------------------------------------------------------- tiwai - 06-27-05 15:59 ---------------------------------------------------------------------- Try the patch in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1192.
