Yes, this works, thank you!
This also explains why -mplay helps: In line 791
"if (!(hdl->sio.mode & SIO_REC)) {" sets "irate = orate;" etc, so
hdl->par.rate would be set to the right value anyway.

It seems like irate and orate, iperiods and operiods etc always have to 
be the same (on the same device) - is this guaranteed to work, or could 
it happen that some soundcard demands different values for input and output?
I mean it works for my device so I'm happy, I'm just wondering :)
