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. ====================================================================== ---------------------------------------------------------------------- Mark Knecht - 10-16-05 16:24 ---------------------------------------------------------------------- So, indeed, alsamixer does now work with the HDSP 9652, at least for some of the global settings that I've normally done with hdspconf. There is a new rate locking option in alsamixer. However, to try it out will require reconfiguring my system to make the HDSP 9652 the primary device. I will try to do this in the next few days. (This response was delayed by problems with the Alsa bug tracking system being unavailable.) ---------------------------------------------------------------------- Mark Knecht - 10-16-05 22:25 ---------------------------------------------------------------------- OK, moderately good news. Turning on Clock Locking in alsamixer does seem to lock the clock down much better, but not perfectly. With the feature turned off I get the horrible noises that I've suffered with for 2-3 years. With the feature turned on I now get just a couple of little sound blips. This is definately usable in a static sense, but it wouldn't be good enough to use in a recording session. Note: I also found today that startine Wine, even when Wine is using the built-in sound device, not the HDSP 9652, causes the HDSP 9652's clock to change frequency and cause the loud noises. With this feature enabled it now just causes the few sound blips. Much, much better than before. QUESTION: How do I turn this on from the command line? I need some command that I can execute at boot time to ensure it's always set correctly?
