Hi!

Not forgotten you lot. Had a lot gone on lately - the old dear(grandmother) spent a couple of weeks in hospital over Christmas - sickness, liquid poops, ended up with pneumonia. I ended up staying up at her place for a few days when she got out. All is good now though. Smile

Still waiting for my insurance to be sorted regarding my motorcycle accident. It's annoying me now. Sad

Should have got my carers allowance sorted very soon now. And it'll be backdated to September last year, which is excellent news. Might have a few spare pennies to get involved in this project again!! Smile

Have had an annoying problem with my M-Audio 7.1 Revolution. The left channel would start crackling at low volumes - quite random when and how much. Which was a real annoyance for me, as I often leave my amplifier turned up and the volume reduced on the PC. It's an oddball layout - DAC -> dual opamp -> another dual opamp per channel. I reflowed the work I'd done previously(all three opamps, with some funky caps on the power rails) - no joy. Removed the dual-opamp from each channel, and the bypass caps, and jumped the output from the remaining opamp straight to the output socket - still no joy. Swapped out the remaining opamp - still no joy.

Then reflowed everything from the one DAC outwards(the card has two, one for primary channels, the other for surround). Problem has gone completely, touch wood. Still running with the second set of opamps removed, and everything is fine. I think they were just there to boost things for a pair of headphones - mine are always powered from my amp, so it isn't a problem.

Lovely sounding card. Smile
