US-428 and n-Track: Bit-Depth Issue?

[sloom]

I've been trying to work at 24-Bit, and I keep getting a Warning window telling me to be sure my soundcard is assigned properly concerning bit depth. The window(s) comes up several times, and then will play the tracks in the timeline window after I make them finally go away. This is a drag to do every time!

I'm using a Tascam US-428, which is a 24-Bit soundcard (24-Bit converters AD/DA). At 16-Bit, everything seems to be fine. I have the 24-Bit n-Track, though, and I've assigned the devices properly, far as I can tell:

I'm using WDM, at 24-Bit individual Mono tracks (not unpacked or justified- don't know what that is anyway). If I use ASIO, that brings other problems, WDM started off seeming to work o.k., but I don't remember what Bit-Depth I was using.... I think 24-.

I'd really like this to go away! Anyone have an idea?

Thanks for your time and expertise!

I can't speak directly to the Tascam, but I do have an M-Audio Omnistudio USB and If I want to use 24 bit I have to go into my soundcards prefs (an M-Audio Icon in control panel) and set it to 24 bit. This enables the interface to work at 16 or 24 bit. I would check the US-428's prefs to see if something similar is needed to work in 24bit

The US-428 does indeed work at 24-Bit, and you can set it up for this in n-Track's Audio Devices settings window- but I've been advised on the n-Tack forum to try using MME drivers instead of WDM. This has worked! 24-Bit.

I can't begin to talk about all these relationships within (this evil little box called) the PC... but there you go.

Thanks for the reply, Sonny.
