Re: ALSA and SCARLETT FOCUSRITE 8i6

[Rodolfo Thomazelli <pe.soberbo@xxxxxxxxx>]

I done the 'git pull' and continued from step 8 of wiki page.

Seems like nothing changes: the device is playing, listed on alsamixer, but not listed on Ubuntu's sound settings. I still can't make my usb device the default one.

*uname -a*

Linux rodolfo 3.9.0-rc3-custom #1 SMP Tue Mar 19 14:48:30 BRT 2013
x86_64 x86_64 x86_64 GNU/Linux

*cat /proc/asound/cards*

  0 [PCH            ]: HDA-Intel - HDA Intel PCH
                        HDA Intel PCH at 0xf7e00000 irq 45
  1 [USB            ]: USB-Audio - Scarlett 8i6 USB
                        Focusrite Scarlett 8i6 USB at
  usb-0000:00:1d.0-1.2, high speed

Any sugestions to make my usb device default? There is some way to do that out of the Ubuntu's sound settings?

Thanks, I'll do that and bring back the results.

There is any other way to teach PulseAudio about change the default device?

Ok, nice. I'll post my two patches then. Thanks for testing!

Well, the thing is that your default device on Ubuntu is in fact
PulseAudio, so you need to teach PulseAudio about a different default
hardware device. You normally do that in the Sound settings, but I don't
know why that doesn't work for you at the moment ...

You go to your linux folder as you did before:

  cd linux

and then you call the command

  git pull

Then you continue at step #8 of the Wiki page ...
