Hi folks,
I have an unsupported USB device (Focusrite Scarlett 18i6), and I was
curious what steps are necessary to get it to work under Linux.
The internal sound card on this machine works well (hw:0). After
loading snd_usb_audio, the 18i6 shows up as expected as device 1:
% cat /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xe2300000 irq 20
1 [USB ]: USB-Audio - Scarlett 18i6 USB
Focusrite Scarlett 18i6 USB at
usb-0000:00:0b.1-8, high speed
But this fails:
% speaker-test -Dhw:1 -c2 -twav
speaker-test 1.0.24.2
Playback device is hw:1
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Playback open error: -2,No such file or directory
The contents of /dev/snd:
/dev/snd/pcmC0D0c /dev/snd/pcmC0D0p /dev/snd/pcmC0D1c
/dev/snd/pcmC0D1p /dev/snd/pcmC0D2c
Plugging the device in yields the following output from dmesg:
[158184.220019] usb 1-8: new high speed USB device using ehci_hcd
and address 20
[158184.372587] 20:1:1 : invalid UAC_FORMAT_TYPE desc

[158184.372845] snd-usb-audio: probe of 1-8:1.0 failed with error -5
I've attached the output from alsa-info.sh.
If it's useful information, I've also booted Windows XP under
VirtualBox (Linux host OS) and was able to use Focusrite's mixer
application, see activity in the meters with a microphone, and hear
differences when changing levels in the headphone out/mic in/etc.
I was not able to play audio or record using the 18i6 through XP,
though. The device does work as expected when running XP as a host
OS.
Any ideas on how I could get the 18i6 working, or is this a lost cause
without documentation from Focusrite?
Thanks,
Nicolai
