Subject: How to create an Alsa mixer for a USB device w/o mixer descriptor?
Date: Wed, 17 Mar 2010 09:37:13 +0100 [thread overview]
Message-ID: <4BA094B9.8010907@web.de> (raw)
Hi,
as posted earlier, I've got a USB device (Fast Track Ultra 8R) wich
*has* a mixer unit but doesn't have a descriptor for it. It's operated
by standard control messages. Although I'm specifically interested in
my device, I guess there are many more USB interfaces out there with
similar issues.
So in general:
What's the best way to build a Alsa mixer for such devices. Should one
bypass all the descriptor parsing and build a mixer specifically for the
device in interest? Or should one think about passing a "fake"
descriptor to the mixer build process?
Any ideas?
Kind regards,
Felix
