I have a laptop running Windows Vista Home Premium 64 bit. The machine is a dual-core Turion64 X2 with 4 GB of RAM. I installed the pd-extended Windows package from "puredata.info". It started up fine, but when I went into the "Media" menu and tried the test sine wave tone, it played, but it was not a steady tone -- it "warbled". I'm guessing there's some other "service" running that's competing with Pure Data for the sound card. Does anyone here have any ideas what I should look for? This is an HP Pavilion dv4 with a whole bunch of HP Multimedia software installed. I haven't tried uninstalling any of that yet.
Meanwhile, pd-extended runs just fine on another (32-bit) laptop with Ubuntu Intrepid Ibex. So I'm not down for the count, but I'd really prefer running under Windows if I can.
