Hello! My WDM audio driver sometimes receives a new stream requests with format descriptor seems to be erratic. In both cases, it's a fully valid WAVEFORMATEXTENSIBLE structure with KSDATAFORMAT_SUBTYPE_PCM. In one case, the Format.wFormatTag is zero. In other case, Samples.wValidBitsPerSample is zero. All other members seems to be correct. In both cases, requests come from the sysaudio (from a system process). Must I accept these requests and get missing values from other descriptor fields or I can reject them?
