Patch which fixes the issue
It seems that the ADPCM driver is making a mess of things because it doesn't properly refuse to convert to the GSM610 format. The attached patch checks the format hint in ADPCM_FormatSuggest(), and will report NOTPOSSIBLE if it isn't in PCM or ADPCM format.
Thank you. Patch works perfectly on wine-1.1.16. ventrilo-3.0.4
