Hi,
Try to record from /dev/oss/oss_hdaudio0/pcmin1 ossrecord -d /dev/oss/oss_hdaudio0/pcmin1 foo.wav Now run ossxmix and see if the vu meters work pcmin1 is controlled by record mix5 which seems to be the internal mics regards Dev Mazumdar --------------------------- 4Front Technologies 9826 Beverlywood Street Los Angeles, CA 90064, USA Tel: (310) 202 8530 Fax: (310) 202 0496 Wannabe Tsotsi wrote:
