hi,
a variation on the usb audio interface theme: i recently
tried the emagic emi2|6 on my powerbook (tibook G4,
debian/unstable/2.6.5), with only partial success.
the device is detected, the firmware apparently loaded, and
snd-usb-audio appears to successfully claim the
interface. however, when i try to use it with jack, jack
bails out because it cannot find any usable sample
format. when playing a soundfile with alsaplayer, i just get
noise; sounds like an endianness problem.
sorry, i can't post any output, as i don't have the
interface at hand. i just wondered if someone has a working
configuration for the emi26 on ppc hardware. maybe some
asoundrc magic is enough?
tia,

The device uses little endian samples, because this is what the USB
Audio Spec says. Jack supports only sample formats with native
endianness. Complain to the Jack developers, and/or use plughw.

Sounds like a bug. Does aplay work?

no, but i don't remember the exact error message. i'll have access to
the device again in a week again, thanks for the pointers.

I've only been able to get the oss drivers to work with my 2|6 on
Linux. While not a cool as jack, they do work very well.
