Hey all...just recently (in the past few days) my Onkyo 595 has started to give off feedback when i turn the volume to level 46 or higher. it starts off faint, then becomes a loud, high pitched squeal that would likely shatter windows. i've never had a problem with this before and have had the volume up to ~70 many times before. i have my computer's sound card hooked up via digital coax and a Marantz CC-4000 via digital coax as well. i only get feedback from the computer (for mp3s/dvds); no squeals from the Marantz, even at 70+ volume levels. i havent touched any cables in the last 3 weeks...this just started happening like 2-3 days ago. i did unplug/reconnect the coax cable from the computer yesterday to try and fix it...no help. anyone know whats wrong?! ------------------ -Thomas Click here to visit my webpage.
