Someone on this list mentioned an article that you wrote about IRQ priority ordering and Latency using lspci. Unfortunatly, I (carelessly) did a Google search with the wrong key words. Your responce (this email) prompted me to look back at the original email. This time I used the correct keywords and it took me right to the HOWTO. It looks pretty promising. I will work with that and see if that has an effect on the situation. I wish I had done this in the first place. I wasted so much time trying to "push IRQ's around" by using the only BIOS setting available ("reserve IRQ for legacy ISA"). Partly what made this useless was that (prior to finding the HOWTO), I wasn't even sure what was a "good" IRQ or a "bad" IRQ. Besides, that was such a hap-hazard way to proceed. > 2) Some other application is stealing cycles I eliminate as much of this as possible by running ecasound without X and as root. But there could be a background process going on. I would assume (by the consistency and predictability of these "interrupts" that it's a problem with data transfer). > a) autorun trying to play CDs automatically I guess I don't understand this. If you're simply referring to the CD player being busy, I'm not running the CD Player while recording. > b) some other app started automatically Certainly possible. Thanks for taking the time to help. I will work with the HOWTO that I found and see how that works out.
