[Alsa-user] Mindprint DI-MOD USB

[Christian Schumann]

Hi all,

this weekend I bought a Mindprint EnVoice MkII Digital Edition with the
DI-MOD USB installed. I can get it to work using the regual usb-audio
driver, but there are still some issues that are quite unconvenient and
perhaps you can help me in sorting them out:

Whenever I connect the USB interface to my computer, the sampling rate
is switched to 96 kHz, which also influences the sampling rate of the
SPDIF output. The rest of my setup is working at 48 kHz, so I'd like the
driver to initialize the device directly with 48 kHZ, and not haveing to
switch the sampling rate manually.

Further, the Windows driver has a switch to enable/disable the SPDIF
output, which I am using. So I had to take the device to a Windows
machine in order to enable SPDIF in the first place. Perhaps this can
also be switched under Linux.

Thanks in advance for your help,
Christian

Ok, so that nobody replied to my mail to alsa-user, I did some research
myself. I contacted Mindprint, and they told me to get into contact with
usb-audio.com. I asked them for specifications, so the default USB-audio
driver could be extended, or perhaps a special driver for the DI-MOD USB
could be written. I'm still waiting for them to reply.
I have never written a driver myself, and my programming knowledge only
suffices to do some minor modifications to existing drivers. So ist
there any developer who would be willing to look at the situation?
