View Full Version : [ubuntu_studio] Sound cards change device numbers every boot.

November 19th, 2011, 08:39 PM
I'm running Ubuntu Studio 11.10 64, with KXStudio PPAs and everything's running smoothly, save one thing:

I have 3 devices installed that the kernel identifies as a sound card: the M Audio Delta 1010LT, the built-into-the-motherboard Realtek "HDA ATI SB", and a video capture card "Conexant CX8801". On every boot, these cards will randomly switch ALSA device positions-- sometimes the 1010LT will be on HW:2, other times on HW:0, etc-- so I have to reconfigure Jack every time.

Is there a way to get them to be assigned statically?

Here, you have everything

I have a regular Delta1010, but it's the same for any card

- output your devices with:

$ cat /proc/asound/cards

Mine looks like this:

0 [M1010 ]: ICE1712 - M Audio Delta 1010
M Audio Delta 1010 at 0xe800, irq 21
1 [Anniv ]: USB-Audio - MIDISPORT 4x4 Anniv
M-Audio MIDISPORT 4x4 Anniv at usb-0000:00:12.1-1, full speed

so in qjackctl, if I want to statically set my Delta1010 to be the audio card, instead of putting HW:0 in, I use HW:M1010

I imagine that the 1010LT might actually be the same value.
