Hi,
I have the same problem with another hardware : Iomega Iconnect. I
notice that sound crackles a lot when using alsa (my USB DAC is an E-MU
0204), but when I use Pulseaudio, sound is great. I don't know why such
a difference.
Maybe, it can help you.
Have you found a solution to your problem
It's a bug in the sheeva kernel
The kirkwood arm cpu doesn't handle Memory Mapped pcm devices.
Version 4.0+ of 'squeezeplug' (http://squeezeplug.eu) has a kernel with
this patch applied.
Here's the patch.
Code:
--- linux-2.6.38.8/sound/usb/pcm.c.orig 2011-06-02
Hi,
Ty for this explanation, but I don't use squeezeplug on Iconnect but
arch linux. I try to understand what you describe and I think the
actual problem is not really there, because some USB audio device can
support mmap, so I think, the solution should be to use a specific
driver for my sound
