Re: [GnomeMeeting-list] How to fix sound choppy on CPU load?



Hi

What kind of soundcard do you have?

Hi Damien,

Thank you for your reply.

That's not normal. I have already used GnomeMeeting on a Pentium 233 MHz
with 64Megs of RAM in the past. Does it only happen on high-activity?


Yes.  For example, a compilation would almost completely
block the sound.  Bursts of CPU utilization (such as moving
around quickly a window in opaque mode) halts the sound and
image movement.  Less than 100% CPU use (such as moving slowly
the window) would not interfere with GM operation.
Disk activity with low CPU usage (e.g., a find) does not
interfere as well.

I also have set up the suggested workaround to NPTL bug
(which improve things for xine's GUI, for example) but it has
no effect.


We have other RedHat 9 users who do not have problems.


I'd be glad to be among them! :-) :-)


I wonder :
- when it happens, does GnomeMeeting take 100% of the CPU?


No, but some other process does.  As soon as the process
consuming CPU stops, the CPU utilization comes down to normal
(roughly 10-20% on PIII 600MHz).


- what is your load average when it happens?


It surely happens when there are other processes requesting 100%
CPU, no matter if I raise gnomemeeting priority to -20.

If there is a process that uses the CPU in bursts of 100%,
the sound choppiness follows relatively accurate the CPU usage.


- are things normal on normal CPU load?


Yes, I have continuous sound and image movement.

Many thanks for your support,

Mihai
