Ok, I updated Ubuntu, and now the onboard device is working again.


With the usb device unplugged:

sudo dmesg -c
[  496.692447] usb 2-1.2: USB disconnect, device number 3



With the usb plugged again:

sudo dmesg -c
[ 1144.857836] usb 2-1.2: new high-speed USB device number 4 using ehci_hcd
[ 1144.951520] usb 2-1.2: New USB device found, idVendor=1235, idProduct=8002
[ 1144.951531] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 1144.951538] usb 2-1.2: Product: Scarlett 8i6 USB
[ 1144.951543] usb 2-1.2: Manufacturer: Focusrite
[ 1144.951547] usb 2-1.2: SerialNumber: 00006B8B
[ 1144.956590] usbaudio: unit 51: unexpected type 0x09
[ 1144.956640] snd-usb-audio: probe of 2-1.2:1.0 failed with error -5



...and the last command:

/proc/asound/cards again.
bash: /proc/asound/cards: Permission denied



Again, in sound controller there is only the onboard device listed.

That recent enought to support your sound card. Unless there is
something in the USB descriptors the driver doesn't like.

It's "/proc/asound/cards", with a leading "/".

There's no need to install any extra driver. But yes, maybe your
attempts to do it anyway made the situation worse.

An update of Ubuntu should give you 3.5.0-26, which also ships with all
stock modules. You can try that. Alternatively, you can try installing a
much newer kernel. You can try if the x86_64 version of these archives
work for you:

  http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/


Once you have your on-board ALSA device back, please try the following.
Disconnect your device, and enter

 $ sudo dmesg -c

... then plug it back in, wait for ~5 seconds and enter

 $ sudo dmesg -c

again. Then send the output to this list, and also check
/proc/asound/cards again.
