But ALSA_WodNumDevs is computed in ALSA_waveinit() , so the waveout_count is
the number of pcm devices in your system

Removing the ALSA_waveinit() imply the driver cannot provide a correct
waveoutcaps to the application since waveoutcaps is computed in
ALSA_ComputeCaps() inside ALSA_waveinit()

This mean that you must configure ALSA to have one sound card with
playback/capture device to test your patch

static DWORD wodInit(void) {
    DWORD i = 0;
    ALSA_WaveInit();
    waveout_count = ALSA_WodNumDevs;

when you have used up the subdevices of hardware mixing sound card,
MMSYSERR_NOTENABLED seem not a correct error

err = snd_pcm_open(&wwo->pcm, WOutDev[dev->devid].pcmname,
SND_PCM_STREAM_PLAYBACK, SND_PCM_NONBLOCK);
    if (err < 0) {
        FIXME("Could not open sound device: %s\n", snd_strerror(err));
        ret = MMSYSERR_NOTENABLED;
        goto error;
    }
