[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
I found a solution in the post http://www.flightgear.org/forums/viewtopic.php?f=2&t=6291&p=52050&hilit=pulse+audio#p52266 (thanks to user macafyc !). The workaround is to create an empty file in the home directory with name .alsoftrc and writing this line drivers = oss. No need to restart. After applied this solution FlightGear won't use pulse and there is no more sound's problem. -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
For information i've got the same problem with the game "Scorched 3D". My other games (GNU/Linux native or Windows native under wine application) don't have any sound's problem. So it seems to be a specific bug for a few applications and not for pulse audio system. Scorched 3D sound's problem is described on internal forum (http://www.scorched3d.co.uk/phpBB3/viewtopic.php?f=6&t=5880&p=56543&hilit=pulse+pulse+audio#p56543). -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
I don't know what I am doing wrong, but the fix outlined above does not solve the problem for me. After deleting the .pulse directory and starting fgfs, I still here sound and the frame rate is very slow, about 1-2 frames per second. My hardware is capable of much higher frame rates, I checked with FGlive, it produces frame rates above 20. Also, the test with glxgears results in more than 1400 frames per second. I am running ubuntu 9.10 on a FSC Amilo laptop with ATI Mobility Radeon X700 graphics card. The Xorg.log file states that the Radeon driver is being used. I would appreciate if you could point at other ways to try fix this performance problem.

[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
I can confirm this too : Flightgear 1.9.1-1ubuntu1 (Ubuntu 9.10). I'm agree with Dmitry Ivanov : if you run Flightgear and looking at volume control applet in tab "applications", ALSA plug-in [fgfs] is blinking ! It seems like connection's problem between pulse daemon and fgfs process. When Flightgear is running pulse audio daemon is consuming about 30% of CPU (Intel Core 2 - 6420 @2.13GHz). Sometimes it could increase to 60%. Dmitry Ivanov's workaround is working perfect (thanks a lot). -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
For now, here is simple workaround: # Prevent fgfs from connecting to PA rm -rf ~/.pulse # Run fgfs fgfs # Restart pulseaudio, recreate ~/.pulse killall pulseaudio -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs

I can confirm this. PulseAudio is very very problematic. I don't know why ubuntu doesn't drop it till it get stable. -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
[Bug 450245] Re: Flightgear uses all CPU available, corrupted sound
The problem is related to PulseAudio. When I remove it, the sound is OK. In volume control applet and paman, this problem looks like Flightgear keeps disconnecting and reconnecting to sound server. -- Flightgear uses all CPU available, corrupted sound https://bugs.launchpad.net/bugs/450245 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/universe-bugs
