Audacity and Alsaplayer Questions

Two questions. 1.) When I fire up Audacity, it crashes Jack and all connections as well, which may or may not crash other apps. I thought Audacity was "Jack compliant" and would work. Why is Audacity crashing Jack? 2.) Seems passing command-line arguments to alsaplayer does not work. Specifically, I'm trying to specify a startup volume. Have tried: alsaplayer -l 50 , 0.5 , others alsaplayer --startvolume 50 , 0.5 , others Also, crossfade (alsaplayer -x) = no joy. How does one specify a start volume for alsaplayer? Does the crossfade option work? Thanks all.

Now that sounds right. At least that is what I'm thinking. Perhaps specifing on the command line? (checking now) I see no command line options to get around this.

Audacity - Jack

You have to specify the output to be jack before using it. The problem - Audacity is killing Jack because of shared resources - Audacity has the audacity to take the card from jack with force... The problem is that you need jack running for the jack port to be available to begin with. No apparent workaround... My suggestion: Use Audacity in non-jack mode for the time being. I have forwarded this tread to the development list.

I wish I could get that far

I wish I could get that far into the program but upon launch of Audacity, Jack is killed. No way to get to it. As well, if I DO manage to get both programs running (firing up Audacity first, then Jack) I have tried to set Audacity's input and output settings to appropriate Jack connections, Audacity crashes on exit and does not save the settings. I'm stuck...

Audacity uses the quite problematic portaudio-system to connect with jack - much trouble bring this can. Just a guess: to connect Audacity properly with jack the sample rate of the Audacity-project you run and the jacks sample rate must be the same.
