Audio Failure

I've lost all audio funcionality. Previously every thing was just fine. The only audio app that works now is Audacity. Ive got an M-audio Audiophile 2496 PCI card, and recently got an M-audio Ozone USB working recently. The only changes I've made are replacing Totem-gstreamer with Totem-xine(for comercial DVD playback) which won't even start anymore, and installing Audacious(cause xine won't play MP3). Audacity works fine, but nothing else. asoundconf list: blank I've tried running alsaconf again and it says alsa is ready to go. Both the Audiophile and the Ozone show up in qjackctl, but jack won't start. Here are the messages: 15:25:23.888 Patchbay deactivated. 15:25:23.920 Statistics reset. 15:25:23.924 Could not open ALSA sequencer as a client. MIDI patchbay will be not available.

Thanks for your input. I got it sorted. When I installed the Madfu firmware loader for the Ozone I think it became the default card. I've learned to switch between them with asoundconf. Easy!. Now I'm trying to set up hotpluging to switch over when I connect the Ozone. Anybody know about the $REMOVER bug in shell scripts. There's a work around here: ... but it's over my head:\ I need to intergrate it with this USB-HOTPLUG-HOW-TO: Thanks, you guys are Rock 'n' Roll! Timing is Everything!

Hi Cinder, I think alsa is

Hi Cinder, I think alsa is OK with your cards but the jackd command options are wrong. In my experience with a m-audio audiophile 2496 PCI card and qjackctl setup, choosing something else than "default" in the input and output channels causes jackd to crash. "-i2" and "-o2" are bad options to jackd. I try to make the setup as simple as possible. For example, in the right column, I only choose the interface (hw:0 in my case) and Audio: Duplex. The remainder is "none" or "default". As far as I know, defining input and out devices only makes sense if you want to use an audio card for capture and other one for playback. I hope this helps.

I haven't got the foggiest idea why that would happen... You can try installing everything again, and install VLC for commercial DVD playback. This would at least keep your gstreamer settings normal. Install and check after each step to see which one breaks your set-up.
