I have a record deck with a USB connection which I last used about 9 months ago. The setup was working then and, as I remember, it was pretty straightforward to set up. Since that time there have been many Debian updates and I'm almost certainly using a later kernel.
When I came to use it this time in conjunction with Audacity, which I was using last time, I can't get a peep out of it although playing sound files, e.g. midi, does work. I have tried various inputs without success. The appropriate modules are loaded including snd_usb_audio. When the USB lead is plugged in I get this in the logs: kernel: usb 1-7.1: new full speed USB device using ehci_hcd and address 6 kernel: usb 1-7.1: configuration #1 chosen from 1 choice kernel: input: Burr-Brown from TI USB Audio CODEC as /class/input/input4 kernel: input: USB HID v1.00 Device [Burr-Brown from TI USB Audio CODEC ] on usb-0000:00:1d.7-7.1 kernel: usbcore: registered new interface driver snd-usb-audio a little further on in the log I see: kernel: cannot submit datapipe for urb 0, error -28: not enough bandwidth Originally I got this in the log: kernel: cannot submit datapipe for urb 0, error -38: enable CONFIG_USB_EHCI_SPLIT_ISO to play through a hub so I enabled that in the kernel and recompiled although I'm not using a USB hub and then got the 'not enough bandwidth' error. I'm running an uptodate (today) Debian Testing with kernel 2.6.22 and Alsa modules. Can anyone suggest what I could do to try and trace the fault as I'm way out of my depth here?
