That's because I gave you the channels you asked for, alsa and dsound. That line would show up in a winmm log.
0020:trace:winmm:WAVE_Open dwRet = MMSYSERR_ALLOCATED
this seem that the program expect the driver support multiple waveoutopen concurrently
the oss driver ens1371 seem support /dev/dsp and /dev/adsp ( not sure the alternate PCM output to the front channels or rear channels )
Take a look at the system diagram of ymf724 datasheet , there are multiple WaveOut device connected to Ds1 slot manager ( up to 64 sound)
