What is your CPU load when you get breakups in the sound? It seems to me you are simply overloading the computer. Regards, Mike -----Original Message----- >From: Panos Katergiathis |

I did as you friends instructed. The lists of my audio devices is: PortAudio: available output devices: 0: Microsoft Sound Mapper - Output 1: M-Audio FW 410 Multi 2: M-Audio FW 410 1/2 3: M-Audio FW 410 3/4 4: M-Audio FW 410 5/6 5: M-Audio FW 410 7/8 6: M-Audio FW 410 S/PDIF 7: Primary Sound Driver 8: M-Audio FW 410 Multi 9: M-Audio FW 410 1/2 10: M-Audio FW 410 3/4 11: M-Audio FW 410 5/6 12: M-Audio FW 410 7/8 13: M-Audio FW 410 S/PDIF 14: ASIO DirectX Full Duplex Driver 15: ASIO Multimedia Driver 16: M-Audio FW ASIO ... so i used these lines to experiment: csound -s -odac16 -b256 -B1024 composition.csd csound -s -odac15 -b256 -B1024 composition.csd csound -s -odac14 -b256 -B1024 composition.csd ... and i also tried to further reduce the b and B parameters. Unfortunately, the problem remains. I checked the CPU load when this happens and it is about 53%. This particular score i am testing with is not mine. I borrowed it for testing reasons. It has a climax (actually several of them) about 1.5 minute after it's started. At that climax i am hearing audio drop-outs whose length differs on some of the above experiments but they never dissappear. Any more thoughts? Panos P.S. What makes me angry that this morning at my office computer (equiped with a Soundblaster card) none of these things occured... :( Michael Gogins wrote: > What is your CPU load when you get breakups in the sound?

Did you try dev2 (which is MME)? Another thing with ASIO is that ultimately, the buffer size is determined by the ASIO panel, so you can try opening it (in control panels) and changing settings. Another thing: try to set the buffersize to be a mulitple of ksmps. Eg. ksmps= 128 buffersizes 512 and 1024 or even ksmps = 64 Victor At 17:05 24/05/2006, you wrote: >I did as you friends instructed. >The lists of my audio devices is: > >PortAudio: available output devices: > 0: Microsoft Sound Mapper - Output > 1: M-Audio FW 410 Multi > 2: M-Audio FW 410 1/2 > 3: M-Audio FW 410 3/4 > 4: M-Audio FW 410 5/6 > 5: M-Audio FW 410 7/8 > 6: M-Audio FW 410 S/PDIF > 7: Primary Sound Driver > 8: M-Audio FW 410 Multi > 9: M-Audio FW 410 1/2 > 10: M-Audio FW 410 3/4 > 11: M-Audio FW 410 5/6 > 12: M-Audio FW 410 7/8 > 13: M-Audio FW 410 S/PDIF > 14: ASIO DirectX Full Duplex Driver > 15: ASIO Multimedia Driver > 16: M-Audio FW ASIO > >... so i used these lines to experiment: >csound -s -odac16 -b256 -B1024 composition.csd >csound -s -odac15 -b256 -B1024 composition.csd >csound -s -odac14 -b256 -B1024 composition.csd > >... and i also tried to further reduce the b and B parameters. > >Unfortunately, the problem remains. >I checked the CPU load when this happens and it is about 53%. > >This particular score i am testing with is not mine.

Allright. The 'ksmps' thing did the work ( with the device #16). Thank you all for your support. One final thing though: If i had bought the Csound Book, would i know all these things? :) Best Regards Panos Victor Lazzarini wrote: > Did you try dev2 (which is MME)?

Well some of these things are specific to Csound 5.

But I think it's in the manual already, as we have seen this before.
