In audio/audio_template.h in the AUD_open_ functions there is one

    ldebug ("open %s, freq %d, nchannels %d, fmt %d\n",
            name, as->freq, as->nchannels, as->fmt);

line. Please replace this line with

    fprintf(stderr, "open %s, freq %d, nchannels %d, fmt %d\n",
            name, as->freq, as->nchannels, as->fmt);

compile and start AmigaOS. Use the default out.buffer-count. I would 
like to know the via-ac97 drivers idea of the sampling frequency.

It would help if I could reproduce this issue on my computer.

With best regards,
