Hi,
I think you can look at /usr/lib/conf/osscore.conf and change vmix to attach to pcmin1 instead of pcmin0 so that now vmix is able to multiplex input and the VU meter can start registering input. You can save the entire mixer setup using savemixer. regards Dev Mazumdar --------------------------- 4Front Technologies 9826 Beverlywood Street Los Angeles, CA 90064, USA Tel: (310) 202 8530 Fax:
