"Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3857" and other warnings are being reported when launching SVN HEAD from the console, but not when launching 1.3.12. See Bug 267. I think these may come from the recent PortAudio update, and that the "Expression 'stream->capture.pcm' error tends to come and go in releases without necessarily implying a practical problem.
Does anyone have any comments, find recording is now not working correctly in HEAD, or find some devices are not being detected by Audacity? Does anyone *not* see these errors?
Thanks
Gale

Re: Warnings on launching SVN HEAD
I usually don't use the svn head except when for testing purposes that have been discussed here in other threads. As I stated in those threads I usually see a lot of those warnings...
I'm not really sure if it affects the recording capabilities of audacity in anyway, I'm not sure if I've done any recordings in svn head.

Include as much details as you can in your post (Audacity version, Operating System, Equipment used, etc).
Please post your question in the appropriate forum (regarding audacity version and operating system).

Re: Warnings on launching SVN HEAD
I'm getting errors when recording using a debug build. The errors occur when the cursor reaches the end of the screen and the screen is redrawn. They sometimes result in Audacity freezing.
Update:
I've just done a fresh build (non-debug) and I'm getting the error message:
"Expression 'stream->capture.pcm' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 3857" on launching Audacity 1.3.13
This message appears once on launch.
Audacity then appears to record correctly with no further errors.

Is Software Playthrough and/or Overdub enabled? What do the errors say? Are the errors repeatable, but not the freeze?steve wrote:I'm getting errors when recording using a debug build.
