control panel crashing

Open Wouter1 opened this issue 9 years ago • 8 comments

Tom reports in #40 that the control panel is crashing sometimes

THis happens when using driver 3.5.1 and changing the rate from reaper

Tom, can you post a stacktrace of the crash?And maybe a zip file log messages during the crash? Maybe you can pick what you think are the most relevant and replace 100's of repeated messages with "..." or something

One theory is that the driver does not completely stop anymore. There were changes in the stop procedure, because the driver now reads more proactively ahead of the completion callback.

This may be related to the problem that switching the sample rate in reaper does not work anymore, since both problems appear in the same driver version 3.5.1

I switched rates a number of times in reaper, every time checking the logs. And then it works fine. I think that what happens is that the audio streams are STOPPED COMPLETELY when you switch out of the reaper app. If you then switch back to reaper the stream is started afresh and then it works fine.

Yes confirmed, if you just switch the rate inside reaper, something goes wrong. If you then switch out of reaper (with nothing playing/recording inside reaper) and switch back into reaper, it starts working again.

This is the message when switching rates inside reaper from 44k to 48k after which audio does not work anymore

This is when you switch with quicktime player 7 from 44k to 48k after which audio works fine

seems that reaper is performing stopUSBStream , then a performAudioEngineStart followed instantly by a stop, and then a start again.

I found the control panel to crash if you turn off the EMU with the control panel still running but its window closed.
