I know my card (ADI 188x WDM) supports it because it works fine with the commercial OSS. In the sample code: fd = open("/dev/dsp", O_RDWR); ioctl(fd, SNDCTL_DSP_SETDUPLEX, 0) I get: SNDCTL_DSP_SETDUPLEX: Invalid argument Also, when using the "rec" (based on sox) utility, my kernel crashes completely (no panic, no oops, nothing else happens). My setup is: Compaq Presario 1720CA PIII mobile 1 GHz / 256 MB RAM ATI Mobility Radeon M6 / 8 MB ADI 188x WDM sound chip (on-board) RedHat 7.2/2.4.17 Can anyone help me? Jean-Marc P.S.
