[LAU] No playback anymore with M-Audio Transit and firmware madfuload

Hi all ! I use an M-Audio Transit at home which was working pretty good for some weeks. However, the playback hangs now... Although the device seems well detected and the firmware loaded, there is no sound playing back anymore. Some consequences of this new bug : - amarok gets the device and seems to play, but I get nothing on the output, - qjackctl detects the card, starts jackd but shows many XRUNs and always 0% as process loading. This bug can be reproduced on Debian Sid and Lenny. May it be due to some new methods used by udev to load the firmware or abnormal detecting by network-manager (see the logs) or a default config using 16 bit word length and not 24 bits ? Can someone reproduce this bevahior using the Transit ? Thanks for your help ! Guillaume Here are my logs : momo@wm16:~$ dmesg [10789.912122] usb 4-2: new full speed USB device using uhci_hcd and address 15 [10790.068078] usb 4-2: configuration #1 chosen from 1 choice [10790.075317] usb 4-2: New USB device found, idVendor=0763, idProduct=2806 [10790.075323] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [10790.075326] usb 4-2: Product: Unknown [10790.075328] usb 4-2: Manufacturer: Unknown [10790.500038] usb 4-2: reset full speed USB device using uhci_hcd and address 15 [10790.637945] usb 4-2: device firmware changed [10790.637945] usb 4-2: USB disconnect, address 15 [10790.752036] usb 4-2: new full speed USB device using uhci_hcd and address 16 [10790.977030] usb 4-2: configuration #1 chosen from 1 choice [10791.047104] usb 4-2: New USB device found, idVendor=0763, idProduct=2006 [10791.047111] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [10791.047114] usb 4-2: Product: Transit USB [10791.047116] usb 4-2: Manufacturer: M-Audio momo@wm16:~$ cat /proc/asound/cards 0 [ICH6 ]: ICH4 - Intel ICH6 Intel ICH6 with STAC9750,51 at irq 16 1 [pcsp ]: PC-Speaker - pcsp Internal PC-Speaker at port 0x61 2 [USB ]: USB-Audio - Transit USB M-Audio Transit USB at usb-0000:00:1d.3-2, full speed momo@wm16:~$ lsusb Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 016: ID 0763:2006 Midiman M-Audio Transit Bus 004 Device 002: ID 046d:c526 Logitech, Inc.
