The first thing I tried was running the compile with pcm instead of snd, as per all the docs but then I got different errors come up, this time during the make. That's the only reason I compiled with snd instead. Specifically, I get a screenful of errors similar to the 2 or 3 lines i've quoted below, and then the build stops: midi_synth.o: In function 'midi_synth_xxxxx': midi_synth.o(.text+0xNNN): undefined reference to 'synth_devs' /* (similar error definitions complaining about other midi.synth.o function calls and undefined references repeated for several lines) */ ending with the line: *** Error code 1 and an abrupt stop to the make. But in any case, it wasnt until I had a "successful" build that I realised no mixer was being created, so then I went back and tried to compile with pcm again instead of snd and this time include the line with options __SGNXPRO__ added for the mixer, but then the build falls over when I run /usr/sbin/config MYKERNELFILE with the exact same error "Unknown option __SGNXPRO__" still cant make sense of this one, all the other documented options i've read about for the sb device dont kick up any errors (but they're not relevant to my card !) thanks in advance John Utz wrote: > > why are you using snd instead of pcm? > > snd is pretty deprecated.... > > i think you will get immediately better results using sbc ( the sb bridge > driver for pcm ) and pcm > > man pcm and man sbc can be your new best friends! > > On Thu, 18 Apr 2002, Jean-Mark Dupoux wrote: > > > Im having problems with an option for soundcard support to put in a > > kernel config file.
