Recording freezes when screensaver is activated

[phabaudac]

phabaudac, what is your "host" and "recording device" in the Audacity Devices Preferences? Try changing Transport > Software Playthrough from whatever state it's in now. If you turn it on, it might stop the screensaver coming on. Or if you turn it off it might stop the freeze when the screensaver comes on - software playthrough has a lot of issues on Linux.

Hello Gale,
The host is : ALSA
The recording device is : C-Media CMI8738: C-Media PCI IEC958 (hw:0,2)
I do not use Software Playthrough. I mean it is disabled in Audacity Recording Preferences, and I never tried to enabled it through the Transport menu. Also, though the Terratec Aureon PCI 5.1 has input monitoring capability I do not use it during long run recording sessions.
I had no time this week to make new trials. I hope I will have some more time for that on sunday. I'll keep you informed of whatever results.

I made a 2 hours recording this morning. The screen saver was disabled. The screen was configured to sleep after 30 minutes. The recording did not freeze at all during the whole recording session. So, I consider this problem is resolved, at least as far as I am concerned...
Indeed, before using audacity I was using arecord (basic ALSA recorder). I never experienced freezing with arecord, even with the screen saver enabled.
arecord being a text mode tool, I think that there might be a wrong interaction between the GUI of Audacity and graphical events generated by the screen saver...

It would help to be clear what version of Audacity you are using. It is 1.3.12 Beta here and "1.3.13 Beta" in the thread where Timer Record fails to stop.

It would be most useful if you could build from latest SVN. SVN for me on Ubuntu 10.04 (built against widgets 2.8.10) doesn't have recording freezes even if a screensaver is used, and even if I use Timer Record.

Sorry I made a mistake : it is 1.3.12 Beta (not 1.3.13 Beta).

Ok, I'll try to compile from SVN.

I just had a look at build from latest SVN but did not see Ubuntu 10.04 (lucid) in supported distributions.
Is this just a matter of replacing "jaunty-wx" by "lucid-wx" in /etc/apt/sources.list ?

The method described should work for any version of Ubuntu 9.04 onward.
For installing WxWidgets you should just be able to replace "karmic" with "lucid" as you suggest and as described here: http://wiki.wxpython.org/InstallingOnUbuntuOrDebian

An easier option may be to use this PPA:
Daily builds for Lucid are available here: https://launchpad.net/~audacity-team/+archive/daily

If you don't want Audacity to be updated daily, disable the PPA repository after you have updated. To disable a repository, open "Software Sources" from "System > Administration".

I'm sorry but I did not know of PPA until I read your post. So I added "ppa:audacity-team/daily" to Software sources. It worked silently for a while and then I closed Software Sources. But now when I open Audacity I still have the "old" release (1.3.12-beta). Is there anything more to do for Audacity being updated ?

I ran the Update Manager and now I have Audacity 1.3.13-alpha. However it is still linked with wxWidgets 2.8.10...

If the building from SVN steps don't produce 2.8.11, then you may well have to compile 2.8.11 yourself and make sure you build Audacity against that version using steps like these.

It's only a theory as yet that 2.8.11 will help this problem.

Sorry Gale, but I can't do that right now. I'll try when I have more free time. I'll keep you informed of the results.
