Hello,

I have an M-Audio Transit that I use to listen to music through foobar2000 0.8.3 (analog out). It works pretty well, except that almost each time I start playback (open an output stream) with less than 48 kHz using DirectSound there is a loud, screeching sound up to about half a second in length. The problem disappears if I upsample to 48 kHz using foobar's resampler. Using wave out or ASIO reduces the sound to a rather silent click, but it is still audible and a little annoying.
All other applications I've tried (Media Player Classic, Windows Media Player 9, foobar 0.9 beta 10) give me the same trouble. An upgrade to the recently released new driver didn't change anything either.
I have contacted M-Audio's support about this, and they advised me to have my retailer check the device. Since this would involve sending it back to the web shop I got it from, I'm reluctant to do this.
I have not had the chance to try the Transit with another system yet, but plan to do so soon.

So my question is this: Does anybody else have this problem with a Transit? Has anyone successfully solved it?


My system:
Acer TravelMate 3200 notebook (Pentium M/Centrino)
512 MB RAM
Windows XP Pro, all updates installed
Newest available drivers for chipset etc.

Sorry for hijacking your thread (kind of, I guess) but I am planning on buying an M-Audio Transit for my Notebook so I'd like to ask you a question.

When using SPDIF Input, does the Transit slave itself to the digital source or will it resample internally like creative cards do?

According to M-Audio, the Transit won't resample during playback over SPDIF out (analog outputs aren't mentioned, though) ... are you sure your Notebook's USB port supplies enough power (these USB ports are often underpowered)?

I have no problem with you, erm, borrowing my thread. But I'm afraid I don't know the answer to your question and don't have the means to investigate it either (no devices with SPDIF output).

I suspected a power problem too, so I plugged the Transit in a USB hub with an extra power supply -- same trouble.

I've more or less settled on using ASIO by now. Ticking "use direct input monitor" in Otachan's foobar component totally eliminates the occasional stuttering, and apart from the lack of a nice fade-in like with DirectSound 2.0, it's almost perfect.

I have a delta 1010 LT and have experienced your same problems. I have managed to mminimize them to the point they almost never happen. I don't know if the transit has a delta control panel like the 1010, but my problems were solved by locking the codec sample rate at 48 kHZ. My guess is the sounds are just the card trying to change its sampling frequency to match the frequency of whatever its playing, but not doing it fast enough.
Hope this helps.

Manuel

Bump! : I'm planning to buy one of those too, does anyone else experience such terrible flaw ?
