->I think audacity uses the OSS emulation layer of ALSA, maybe there is a new "feature" (bug?) in the newest ALSA that breaks emulation for the HDSP? What sort of message do you get on startup? -- Fernando<- That's just it - there is no startup. It just hangs there with no message or any activity at all - until you interrupt the process or kill it in another shell. I'm going to try downgrading to the "latest stable release" (which is earlier than the 1.1-3 version on planetccrma) when the audacity site is back up - where did the ccrma audacity come from? Thanks, Matt
