Hi all,

I use different sound cards here, from PCI (Marian and ESI) to PCI-E (Orban) to firewire and the last one a M-Audio 2626 Profire has a strange problem if I use or normal out or the ASIO option and 192Khz sample rate, ST gives a lot of buffering problems when I send out the composite signal to the transmitter, in fact with latency above 2 seconds the problem remains. Seems 192Khz is for this type of soundcard a overload. I reinstalled the suitable latest drivers. But seems a no go for this one.
I have also 2 Motu firewire soundcards (normally for the playout system) and these don't have the problem with ST, even better with these I don't need ASIO at all because I can use almost 0.2 ms as output buffer.

Does anyone of you users also use a firewire device to feed a transmitter? And do you have problems with it?

I hope you can advice me

Thanks
Gunther

Have you tried it with another program instead of Stereo Tool? Just generate a 192 kHz file and play it with any player.

it's the same with other software, changed the FW cable too, seems 192Khz is a problem (in other modes it's good), so there are a few causes, or the drivers has a bug or the interface internal has a problem.

[edit]
I noticed also my PPM correlation meter goes crazy (full to the right side) with Winamp, Media Player, Audacity via the M-Audio interface. Same WAV files (stored on a apart server) played on another PC via network is total different
Gonna e-mail M-audio about the issue. They have to rebuild a driver for Win10 anyway. If than the problem remains I think it's time to send it back to my audio provider (it has still warranty)

Thanks

Can you rise samples for latency on that soundcard? 256 should be enough.

Hi Bojcha,

it's set to 256 since I use it, here are the settings.
It routes also to only 2 output channels, the rest are disabled.

I e-mailed M-Audio, but still no response from them.

Yes, even to 4096, since M-audio isn't very cooperative in this, I send it back to my dealer.
Never had issues with M-Audio (I still have a FW Audiophile in my home setup and 2 keyboards) till I bought the 2626 in the beginning lot's of bugs and crashes in the drivers and now this.
Return to sender and I hope I get some answers via my dealer.
