Happens for -f dat, cd, S32_LE, -D hw:0,1, plughw:0,1, iec958, spdif. I can boot into Windows without doing anything to the hardware and successfully record. -- imalone _______________________________________________ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
