hi there, pls check kx 3538k release: http://download.kxproject.lugosoft.com/downloads/kxdrv3538k-full.exe previous build (3538j: http://www.driverheaven.net/showthread.php?t=97845) please review this link for details. also read Project Status note: there were NO significant changes in this version, except additional a2zs notebook features + some minor sb0610 (a4 value) initalization issue (I added an option that might affect digital output / line input - please check). -- asio code is the same. I will probably check 3534f-3538 difference soon; ac3 decoding stability -might- have improved (pls check) -- as usual, no 24/96, 64 bit, EAX2 etc.. -- please check this build. try to reproduce BSOD issue with volume controls (I have never been able to do this myself): turn off automatic reboot (control panel - system - advanced - start-up and recovery: uncheck 'automatic restart', choose 'small memory dump') - if managed to, find minidump (usually in your c:\windows\minidump folder), WinRar it and send it to me with full bug description (include all BSOD numbers!) -- known issues with a2zsnb and supported features: - I cannot make analog inputs work. at all... - SPDIF input/output + all analog outputs should be o.k. - on the 'ins and outs' page there are invalid inputs + graphics for testing purposes. SPDIF Input is accessible as 'Generic' input. - on certain chipsets a2zsnb produces the same 'constant noise instead of audio'. this might require PCI latency modifications. please review the thread in 'bug reports' forum and let me know if you manage to fix the issue. at the moment, it is possible to fix this by running 'kxctrl -rv' AND/OR playing a MIDI file AND/OR enable/disable device (don't forget to unload kxmixer first!). "kxctrl -shw 22 value" will change input source (at least, will try to: values are 0,1,2,3 -- this doesn't work, unfortunately, but keep trying. review ALSA drivers if you have enough time. latest build, 1.12?, does not support line input, if I'm not mistaken) -- future plans: I would like to release 3539 officially, based on 3538k, provided we fix BSOD issue. no additional features are expected in 3539. there will be NO 3538 final, the next stable build will be 3539. after that, I really hope to start working on x64 version of the driver, provided I get the hardware (might take 1-2 months). Vista support -might- come later. -- good luck and enjoy -- as always, any updates, new code, new effects, translations, whatever, are welcome. pls send them by e-mail. pls check 'delivery report' in your mail client to ensure I received your message.
