I have problems with my D820 that I canít correct no matter what I try.
Audio dropout is the symptom and happens in any application that uses sound: Sonar (recording application), Forte Performer (soft synth hosting application), Windows Media Player, watching movies or videos online, etc.
Iíve tried adjusting latency, experimenting with the buffer, and lately bought a new Hard Drive that will be dedicated to just audio (ie: no internet, no network connection to my Desktop, no superfluous software, etc.
I canít even get it to work correctly with this new drive which has nothing else on it but the Edirol UA-25EX soundcard! The only thing I can think of is perhaps itís something to do with IRQ. Is there a way to force the assignment of a lower number?
Whenever Iíve installed the Soundcard, (and from what I read, because of ACPI), it just installs down at the very bottom of the IRQ list. I donít really understand this stuff, but from what Iíve read (the M-Audio site has an article on IRQís), you need an IRQ slot of 15 or lower (physical IRQís), and one that isnít shared.
The IRQ assignment is low (23, which would make it a virtual IRQ, and itís all the way at the bottom of the list).
Iíve checked per the M-Audio article, and although itís not shared with anything, the article also mentions that you canít see if a virtual IRQ is shared. How can you reassign to a lower IRQ if you have no control over the assignment to begin with?
Iím not even sure this is necessarily the answer to my woes, but itís something I havenít tried. As you can see below, there should be more than enough processing power to run a few soft synths inside of either Sonar (Home Edition) or through the hosting software Forte Performer.
Iíve been using the USB connection in the back of the computer (which is dedicated to the soundcard only) because a few people online mentioned that the ones in the back are more ďdirectly connectedĒ, whatever that meansÖ.
