M-Audio FastTrack Ultra and Jack/ALSA
Hello, so I picked up an M-Audio FastTrack Ultra on the whim of it being a "plug & play" USB 2.0 audio interface with the perfect amount of I/O's. I'm having trouble getting Jack to cooperate with it-- It instantly recognized the device as hw:1, the server crashes on startup... Are there some kind of drivers that I need to install for a USB interface?
Thanks for any insight.

Could you post the jack output ?dArAzAc wrote:Hello, so I picked up an M-Audio FastTrack Ultra on the whim of it being a "plug & play" USB 2.0 audio interface with the perfect amount of I/O's.

anyway.. other suggestions:
(1) check in /proc/asound/cards that your m-audio has the id # (where # is the number in hw:#)
(2) make sure that the identifiers of the input and output interfaces are right (hw:1,0 , hw:1,1 , ...)
(3) make sure that your card runs with a high rt priority
* sudo lsusb -v ---> should tell the usb port where your card is connected to
* cat /proc/interrupts ---> should tell the associated irq
* Now i don't remember exactly how it is done to check a thread's priority with 'ps'.. but I'm sure that there is a way to do so.
Hope it helps
Gerard.

Re: M-Audio FastTrack Ultra and Jack/ALSA
That's pretty strange: I don't think I've seen /proc/asound/cards and 'aplay -l' disagree before. When I unload my soundcard's module, it disappears from both /proc/asound/cards and aplay.dArAzAc wrote:/proc/asound/cardsI think that the issue is ALSA not recognizing the card:Code: Select all

Perhaps ask the alsa guys? I seem to remember they have a quite active irc channel and mailinglist.

I'm now convinced that the issue lies in this somehow, I'm trying to get help via the ALSA IRC with no luck, hmm.raboof wrote: That's pretty strange: I don't think I've seen /proc/asound/cards and 'aplay -l' disagree before.

Re: M-Audio FastTrack Ultra and Jack/ALSA
Right - so there really seem to be 2 cards - perhaps there are no PCM devices recognised on the second one? Could you paste 'ls -alFh /proc/asound/card1' ? Normally it should include at least one 'pcm*p' directory.dArAzAc wrote:Code: Select all
