Another short addendum - I tried doing a bunch of: amixer cset numid=5 27,0,32768 incrementing the first 2 numbers (27,0) so that it would route all the adat outs - that yielded the same results in ardour - I'm not even sure if Mark was sure if this was the right wording for the amixer command -- -------------- Aaron Trumm NQuit www.nquit.com --------------
