Re: [Alsa-user] USB audio device that works for recording?

[John W. C. <jo...@co...>]

My suggestion might be blasphemous to the true audio professionals, but I
have been very pleased overall so far with my Soundblaster Audigy 2 NX
device.  It has the potential to do 96KHz, 24-bit playback and capture.  I
have recorded at 48KHz 16-bit from its line in jack, and the quality was
excellent.  And while I was playing back 48KHz 16-bit at the same time. 
And only at USB 1.1 full-speed isochronous.

Concerning USB 2.0, I have upgraded the NX's firmware to the 12/23/03
level that should support USB 2.0, but it's still a 1.1 device under
kernel 2.4.22.

Does anyone have this device working as USB 2.0 on Linux?  One possible
explanation is that kernel 2.4.22's USB drivers don't have "other speed"
(USB_DT_OTHER_SPEED_CONFIG) support, and Creative might have implemented
support for USB 2.0 this way.  A later 2.4 or 2.6 kernel might "just work"
at USB 2.0, or does the snd-usb-audio driver have to get involved in this
negotiation?

Thanks!
John
