Hello, Following up on my post about `set_params:901: Sample format non available` I did some tests which I posted here. The outcome was that I could record, even in 16-bit, but not in stereo. Stereo would yield silence. Does anybody here have the M-Audio DIO2496 working for recording from spdif? If so, please post. Below are the tests I did. Thanks, Udo >> Yes. Use plughw:1 rather than hw:1. Or just use default:1 for >> > > automatic rate, format, channel conversion and dmix. Thanks for the tips. I did some tests.
