Thanks Lars - I'll test once a set of headphones with a 3.5mm socket arrive. I'm sure I must have a pair somewhere, but couldn't find them when I went looking this morning...

David McKenna:
Thanks Lars! For playback, SVN2400 works well using either USB2 or USB3 port, system sounds, PM123 and Youtube all work. Haven't figured out how to record yet... when I try creating a 'new' file using WEPM, I get an error saying 'unable to open file.wav' and it creates a 0 byte file. Any hints how to record a file?

Regards,

Hi David

On January of 2021, I was testing a USB mic to record audio. (I just tell you date, to let you know I'm not very fresh with the procedure).

I remember I used DTAPE and put some specific settings.

For the USB device I used PCM, 44100 Hz and 48000 Hz, 16 bits, Mono, Line in.

Remember that on DTAPE you need to create or open the file first, before recording, if I recall correctly.

 Thanks Martin! DTape works to record with my Behringer unit, but only on a USB2 port. On USB3 ports it does not get a signal from the unit to the program. Maybe a limitation of the base USB3 driver (which expires in 3 days...)?

Regards,

WEPM.EXE is a lousy tool. You have to call it with some temporary file name for recording purposes (say: "tmp.wav", preferrably on a RAM drive or so) from a commandline (or via a customized program object).
If you do that it will create that temporary file with that name when it opens. You can then set all the recording settings and record. Once you stop recording, you can do a "Save copy as" to save to a file that you actually want to keep and then leave the tool with "discard" (to basically drop the temporary file).
