Hi. i have this problem with my ZxR i recently bought: Whenever i play games (any game) or listen to music, after some time of normal playback sound get really weird, like distorted, crackly but actual sounds are somewhere back there. When i stop the game or the music, sound is then, totally gone and in order to correct this issue i need to reboot and then back to normal. This is not a regular thing, it's not always happening. Today happened 4 times in 4 hours (annoying) but i also might spend days or weeks and everything's normal. Any idea what's causing this? I have a Asrock Z97 extreme 4, i7 4790k, 16gb ram 1600, SSD (OS naturally) and two hdd, GTX 970 and a 550w Antec Power Supply. 5.1 Logitech speakers and HD598 headphones (im using the knob/mic hardware for headphones: everyone says it degrades sound, i've tested a lot and with a little EQ tweak, it sounds just as great as directly from the sound card... maybe the headphones responds great). I've changed settings inside the sound card such as 44.1@16bits / 96@24bits and the same issue... checked everything inside pc and everything it's ok. i started to believe it might be power supply issues? is it possible? i have a battery UPS on my pc and on full stress it works great. WEIRD thing is: before this sound card, i had a X-FI pro xtremegamer series and had a similar issue: high static sound for less than a sec and no sound, reboot and back to normal. and the same behavior than ZxR... might work great for long periods of time, might screw my patience out the same day. i don't seem to find a similar issue on the internet because ppl say they resolve this issue uninstalling onboard audio from win and Bios... before installing my SoundBlaster cards, i uninstall everything, drivers completly from win and Bios deactivated onboard audio, my channels do not swap. BTW, i'm using latest drivers on Creative web page for Win7 64 bits. Sorry for long post, but felt like i needed full background to have context of my issue. THANKS really!. jprkgc.
