Hi there, I'm having troubles with linking the pcm timer to the midi timer for a SB Audigy. I slightly adapted the code of Steve deRosier [http://thread.gmane.org/gmane.linux.alsa.devel/22156/focus=22160], my function is listed below. While it works with an ES1938 card, it doesn't with a SB Audigy: If I'm trying to record audio (generated from a midi signal I'm sending from the same card), I only hear the first note sent. Obviously the timing is completely wrong. The problem doesn't occur for pcm playback. Unfortunatly, I didn't find much documentation about cards, devices and subdevices. Do I have to choose a particular one for the Audigy? Why the "SDevice = SDevice << 1;" statement? Where can I find documentation on this topic? My system: alsa 1.0.11, openSuSE 10.1 Any hints are highly welcome! Thx a lot, Gerald bool SmSeq::LinkPCMTimer( snd_pcm_t* pcm ) { // get pcm info snd_pcm_info_t* PCMInfo; snd_pcm_info_alloca( &PCMInfo ); int err = snd_pcm_info( pcm, PCMInfo ); if( err < 0 ) return false ; // get the info we need int Card = snd_pcm_info_get_card ( PCMInfo ); unsigned int Device = snd_pcm_info_get_device ( PCMInfo ); unsigned int SDevice = snd_pcm_info_get_subdevice( PCMInfo ); SDevice = SDevice << 1; // ? if( ( Card < 0 ) ) return false; // setup the data that links us to the PCM snd_timer_id_t* QTID; snd_timer_id_alloca( &QTID ); snd_timer_id_set_class ( QTID, SND_TIMER_CLASS_PCM ); snd_timer_id_set_sclass ( QTID, SND_TIMER_SCLASS_NONE ); snd_timer_id_set_card ( QTID, Card ); snd_timer_id_set_device ( QTID, Device ); snd_timer_id_set_subdevice( QTID, SDevice ); // setup the actual timer snd_seq_queue_timer_t* QueueTimer; snd_seq_queue_timer_alloca( &QueueTimer ); if( snd_seq_get_queue_timer( seq, queue, QueueTimer ) < 0 ) return false; snd_seq_queue_timer_set_type( QueueTimer, SND_SEQ_TIMER_ALSA ); snd_seq_queue_timer_set_id ( QueueTimer, QTID ); snd_seq_set_queue_timer( seq, queue, QueueTimer ); return true; } ------------------------------------------------------------------------- Using Tomcat but need to do more?
