That'd be a dependency nightmare on Fedora Core :/ alsa-lib is patched and installed, but I'll double double check it tomorrow (today's been too rough; had to evactuate rehearsal room and guitarist breaks his little finger). > You won't be able to record for long like this.

Since I don't have any external S/PDIF sources yet, I guess I'll have to wait until/if a solution for 1010LT cards has landed.

Done, but no change. I'll try making sure alsa-lib is patched alright. Thanks for the help. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
