Both XP machine sync to the HDSP 9652. When no specific audio apps are running on the Linux box then this configuration will work for hours if not days with no problems. All audio data from GSt flows through the HDSP 9652's hardware and the hardware mixer sends it on to the Pro Tools box. It works perfectly. When Mozilla is started and I switch from page to page, after a few minutes I will receive a message on the Pro Tools box that the clock supplied by the HDSP 9652 was invalid. I can browse the same web pages on either XP box and I do not corrupt the clocks. ====================================================================== ---------------------------------------------------------------------- tiwai - 10-05-05 18:50 ---------------------------------------------------------------------- ... because no one tried the patch! I can't include it without confirmation that it works. ---------------------------------------------------------------------- tiwai - 10-12-05 14:17 ---------------------------------------------------------------------- Grrr, apparently I'm wrong. It's already in the latest tree :) You just need to turn on "Sample Clock Source Locking" switch on a normal mixer app. Issue History Date Modified Username Field Change ====================================================================== 01-14-05 18:35 Mark Knecht New Issue 01-14-05 18:35 Mark Knecht Distribution => FC2 01-14-05 18:35 Mark Knecht Kernel Version => 2.6.8.1-1.520.2vS7.ll.rhfc2.ccrma 02-01-05 21:35 charbonnel Note Added: 0003466 02-01-05 21:46 Mark Knecht Note Added: 0003470 02-01-05 22:03 rlrevell Note Added: 0003471 02-01-05 22:07 charbonnel Status assigned => resolved 02-01-05 22:07 charbonnel Resolution open => not an issue 02-01-05 22:07 charbonnel Note Added: 0003472 02-01-05 22:12 Mark Knecht Status resolved => feedback 02-01-05 22:12 Mark Knecht Resolution not an issue => reopened 02-01-05 22:12 Mark Knecht Note Added: 0003474 02-02-05 10:20 tiwai Note Added: 0003477 09-19-05 09:58 jdthood Note Added: 0006277 09-29-05 00:30 Mark Knecht Note Added: 0006411 10-05-05 18:50 tiwai Note Added: 0006436 10-12-05 14:17 tiwai Note Added: 0006466 ====================================================================== ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl
