[PD] GEM causes soung glitches

[Ingo]

I have to fully agree with Iohannes.
I have a huge patch that works perfectly the same with and without GEM
running as a second patch.

However, recently I had to change the hardware and I'm having problems now.
This is neither a problem with GEM nor with the patch.
It's a hardware driver problem. The proprietary ATI drivers were not working
with this mainboard so I used the Ubuntu drivers which are no good - and I
get drop outs much earlier than before.

The more complex the patch gets the more important it is to have a perfectly
working system and hardware.

There is nothing you can fix in GEM if you have bad drivers or a badly
designed patch.

There are already a number of ways to set priorities in the system e.g. by
setting up a low latency or realtime system with the best options, the Pd
startup flags as well as patch design.

Iohannes,

I am very sad to listen these words from you. I am just trying to point to a
problem that I feel is important: making sound and work with gem causes
glitches in several scenarios. It is a main problem for me and for some
people I know.

I accept that you think I am not a professional as you are and I also accept
that I have all sort of design problems. No problem. 

But we have a problem here. I am just trying to wave the priority.

I cant help solving the problem directly. My programming skills are not so
good. But if you want I can do other tasks, try to raise money, I dont know.
How do I start?

I would like to ask you, in a very kind way and very friendly. Try not to
reply posts like that suggesting that I am not professional or etc. It makes
people afraid of contributing. Please, call me anything but let people
express their opinions without being hit by emails like that. I am saying
this waiving a white flag :-) Pleaaaase!

All the best

Luiz

most likely, you have a serious design problem.

then you do you have a serious design problem.

the fact that it is a "rarely documented problem" makes me think that
the priority need not be as high as you suggest.

in the meantime, raise the audio buffer of Pd.
(and get yourself a decent gfx card with some proprietary (shudder)
drivers).

having said that, there is certainly loads of things to improve.

since you seem to be "working professionally in complex" scenarios, i
would like to invite you to help solving the problem (in a way that
doesn't break everything platform X)
