Dear Maintainer,

with the new version 1.3.7 of audacity shipped into Sid in the last weeks,
I've notized a strange behavior of this program on my 64 Bit Machine and also
on my Thinkpad R51: When I play normal audiofiles with it, sometimes the
program stopps unexpectedly. The Play button stay pressed, but it is not a
total crash. I can press Stop and then start with play normally from that
position, where audacity has hanged before. Let me specify "sometimes":
Audacity do that sometimes, when I open annother applikation, but also
sometimes, when I do nothing other on my machine.

With older versions of audacity I have not had such effects.

I use for playing and recording the setting "alsa default", my system is an
up-to-date Sid / sidux.

I hope this report is usefull for you. Please tell me, if you need further
information.

With best regards,
  Holger

Can you try to reproduce it with version 1.3.9-1?

Just gave it a try.
Still the same hangups for me.

Note that audacity CPU usage drops to a "idle" level,
while Xorg stays quite high (~50% on my athlon XP 2000+)
Xorg CPU level drops to 3-5% when I press STOP.

Also of interest: I'm using a SB Live (hw1:0) with my audio system;
I also have an integrated soundcard (hw0:0), with same behavior.
HOWEVER, when selecting "default" rather than (hw0:0) as the playback
device, I don't have any trouble.

Sorry for lack of config info, I do not have internet access at home.
(Debian Sid)
I will check this report regularly.

I have found a workaround:
explicitly state a default in .asoundrc:


pcm.!default {
   type hw
   card 1
}

ctl.!default {
   type hw
   card 1
}


and choosing default in audacity does the trick on my desktop (w/ card 0 & 1)
and my laptop (w/ card 0).
