Hi all, Yesterday I was giving an introductory course on Pd and a couple of students who had ACER laptops running windows xp had really audible glitches when playing only sinewaves. Is there something to be installed to the computer to avoid this? Is it supposed to be a know problem?
Thanks
Hello, maybe it was the delay (msec) in the Audio settings (under Media) that was set too low? If set too low this can happen.

They used the default settings, which should be 20, right? I mean, they didn't change anything, it was their first encounter with Pd.

Yes, I think default is 20 msec, they can anyway change to something 50-100msec just to see if the glitches goes away. If the laptop are slow it might help. I´d say give it a try first... then continue with other things.
All the best, Björn

Hi Alexandros
An audio recording of the glitchy sine tone might give some hints what could be wrong. Knowing the supposed frequency might also be helpful for diagnostics.

Next class is next Saturday. Frequency was around 200 Hz or something. I've just sent them an email telling them to try Bjorn's solution. We'll see if it works.

It might work better if they install ASIO4ALL (http://www.asio4all.com/), then adjust the buffer sizes in the asio4all dialog until it doesn't glitch.
