Fire wire 410 & Vegas error

can some one help me with some Firewire 410 issues.
First of all i am having a bit of memory lapse.
question 1:
I know that teh default audio settings for is HDV 44.1khz.
but the audio on M2t files is 48 khz so what should you set as the default?

question 2 when set to 48 khz and I attempt to play file vegas gives me a error thatthe audio playback device does not support the sample rate (details):
"The ASIO device M-Audio FW ASIO does not support the current sample rate "
Vegas audio is set to use audio device type "m-audio FW ASIO"
when i open the FW control panel its showing sample rate detected as 44.1 and doesnt change to 48khz. I do not have ASIO "disable direct monitoring" checked .

Wondering where my problem lies?

FWIW I have the same set up at home and never get this message.

What have you got the 410's sync source set to, Hardware tab on the 410 control panel? Set it to Internal and optical, assuming there's nothing on the optical port.

Also try COLD boot with ALL firewire devices ON, you may need to unplug the PC to force the 410 to reload it's firmware.

Also disable ALL Windoz sounds, they're all 44.1KHz and cause grief, only for a few milliseconds but boy is it annoying.

The default audio sample rate for HDV is 48KHz, to the best of my knowledge. The CD sample rate is 44.1.

There are still many soundcards out there which only accept 44,1 kHz sampling (and this is the reason Vegas starts with 44,1 kHz project property in standard). If you got such a soundcard you are stuck with this setting. But there should be no problem if only you adjust Vegas the way your soundcard requires. Leave the project property set to 44,1 kHz in this case.

Er, the 410 is good for 24/96K. Doesn't really matter much what the Vegas properties are set for, it'll set the 410 (if the 410 is configured right) to sync to the project rate.
The only downside is you're forcing Vegas to do more work for nothing. If the project properties are set to 44.1 and everything on the T'L is 48K then apart from playing back the video Vegas also has to resample the audio. Have lots of audio tracks and it all mounts up.

Bob You are the winner!! It appears to be the windows sounds i thought I had them disabled , but there were a few that were still enabled. reset it to none and saved that as profile. and so far so good. and it appears to be switching to 48k when I set my properties to that and play hdv file.
that is the way I prefer it as I thought and you confirmed that HDV project should be 48 to match the files.

Thanks again Bob!

I would repeat again. Make certain you have ALL 1394 devices connected prior to boot. Failure to do so will produce sonic destruction, I've had the 410 / Vegas mix up audio and video devices, very ugly experience.

Speaking of which I was just reading the manual for my new HVR-M15 deck and Sony specifically warn that pluging / unpluging a 1394 device while either end is powered can easily destroy either the device at either end of the chain. They state that a voltage of upto 40V might be applied briefly and that's enough to crisp something expensive. Clearly these things are "plug and pay".

Now I've never had or heard of this happening 1st hand although there's some similar stories over at DVInfo regarding crisped Canon 1394 ports and Canon saying, sorry not covered by warranty, so there could well be some merit in the Sony cautions.
