      Hi Andy. From what you've said, it sounds very much like a buggy driver. Personally, I'd be inclined to see if there is a more recent driver available from the chip manufacturer. If still no improvement, then an email to Alex is an idea.

      If I try to start up CW Skimmer with the input set to WDM with the SignaLink USB (which only supports MME), I get:

      "Cannot negotiate input format with 07 USB Audio Device: error 1169"

      This suggests to me that your driver does support WDM, but it's not working properly.

I am not sure if I can verify that the drivers specifically include a WDM driver, I just install the driver package supplied . When I switch from MME to WDM, it works for about 2 seconds then CW Skimmer makes weird noises and quits.

Should I be looking for a specific WDM driver for Sound Max or would one expect the generally supplied driver to already support WDM ?
