Subject: M-audio fasttrack pro, input device index
Date: Tue, 27 Mar 2012 08:40:36 +0200	[thread overview]
Message-ID: <4F7160E4.8030506@canonical.com> (raw)

Hi,

M-Audio fasttrack pro has two stereo outputs and one stereo input. It 
looks like the input sometimes shows up at device 0 and sometimes at 
device 1. I e, a device string would sometimes be hw:1,0,0 and sometimes 
hw:1,1,0. (Assuming the card index is 1)

Do we know if there is a reason behind this behaviour, or should we just 
try both device strings?

I don't have this device myself, so I don't know if it's consistent 
given a specific physical device, if it differs between kernel versions, 
or anything else. I've just seen both.
