Hello! I am writing a new driver based on the AC97 sample (WavePCI). In my InterruptServiceRoutine I demand a that->Port->Notify (that->Streams[PIN_WAVEOUT_OFFSET]->ServiceGroup); !AND! a that->m_Port->Notify (that->ServiceGroupWave); to have an additional Service get called in my CMiniportWaveICH (I need this); I observe that my CMiniportWaveICH::Service() gets called, but not the CMiniportWaveICHStream::Service(), where I'd like to Release and get some mappings. Anybody has an idea why ? Markus. __________________________________ Do you Yahoo!? The New Yahoo!
