Hi,
2 similar threads from burningfeetman & gearaddict appear to touch on this subject.
Old system dual core Athlon64 AMD XP SP2 on Gigabyte hardware was rock solid with 2 x 1010LT & all drivers ( from V4 up). No issues and was very happy.
Needed to upgrade to Gigabyte EP45 extreme intel quad core 4 Gb RAM SATA etc. as per signature. Now random heavy distortion / buzzing / crackling / popping / noise on 1010LT output. Specifically the SPDIF to external A/D.
Context: Running Ableton Live 7 with Native instrument plugins. Some external audio inputs to the 1010LT sequenced via external midi interfaces.
using the SPDIF output on the 1st 1010LT for audio monitoring. Its v difficult to isolate this problem but so far:
when all audio is generated internally in ableton live, or I am simply playing back .wavs in adobe audition, there is no problem. there is likewise no issue with any MOTU firewire device audio playback. (disconnected for all the following tests)
When I am recording external audio and playing back audio / soft synths simultaneously in Live, then the problem appears and audio output is heavily distorted.
frequently, the heavy distortion starts when I click a window, change a windows, or popup plugin windows within live.
the only method ive found of resetting to non distorted playback (in live) is by going to m-audio delta control panel and changing ASIO/WDM buffer size (albeit a temporary change as live resets it back to what the size was originally). i do this on 1010LT card 1 where output audio is generated. this usually works for about 30S or so.
This led me to explore the sync source. originally both sync sources were at internal. I connected external wordclock out on 1010LT1 to external wordclock in on 1010LT2 , and changed 1010LT 2 sync source to external wordclock. The behaviour of the problem was different ; less frequent sudden distorted playback, but more distorted when it happened. No idea if this is significant or not.
I needed to rule out there was no audio card hardware issue, so bought a new 1010LT card, and replaced first 1010LT1, and when that made no difference, replaced 1010LT2 with the new card. my conclusion ; not related to failed maudio hardware.
Im running board on latest bios & and latest MOBO drivers.
Have examined interrupts; the cards are on virtual interrupts, and theres nothing I can do about this.Its a quad core intel box. removed any other cards except PCIE graphics card. - Havent swapped out the graphic card for another one yet.
was originally on XP SP2 but upgraded to SP3 to get latest 1010LT driver in the course of trying to fix the problem.
Have moved cards around the slots (there are only 3 PCI slots, 2 used by 1010LTs, other spare)
The MOBO is capable of overclocking but all o/c functionality disabled as is all power saving functionality.
Im going to try and roll back the driver like was mentioned on the forums already. Failing that, Im out of ideas other than replace the MAudio hardware with other non M-Audio PCI soundcard hardware and see if it works.
Anyone got any further ideas? Anyone have this problem on the new intel quad core processors running on gigabyte MOBOs?
Any feedback super appreciated. Thanks.
