I am using the nice program of W.M.Quarles with some own modifications, e.g. I open the dev /dev/dsp I check settings with ioctl SNDCTL_DSP_GETFMTS I see that it is possible to have STEREO-sound ... ========>snip Operation <AFMT_MU_LAW> is possible!

Operation <AFMT_U16_BE> is possible! ========->snip I use ioctl with SNDCTL_DSP_CHANNELS and get the chip is set to MONO I try to set it to STEREO with SNDCTL_DSP_STEREO and get the following message (programmed by myself while analysing the retured bit-pattern: Mono is set I try to set: Stereo Success of Channel-Set: Mono is set Which I interpret as: it is not possible for me to set the STEREO-Bit even as superuser.
