I have an asus m4a785td-evo motherboard. I am using onboard video and audio. I am sending a two channel stereo signal from the computer via the 1/8 inch plug splitting to a dual rca connection to my receiver. My problem is when I initially boot, I only get sound out of one channel. Then if I reboot, or sometimes it starts itself after a few minutes, the audio is perfect and it stays that way for as long as I want to play music. I have installed the most current audio drivers
and even went back to the previous edition driver
and tried that. I have two zones of speakers and both work fine. The receiver has no problems. It seems like it might be a driver issue, but I have tried all the drivers I could find. There are no warnings in the device manager and my settings for stereo playback are correct. I have an old Creative Audigy sound card I can install and bypass the onboard sound, but I hesitate to do that because it is a hassle and I hear Creative comes with loads of bloatware that is difficult to get out of your registry. Can anyone help? I also discovered recently that double booting does not always result in both channels working, but eventually the second channel comes on, usually about 10 minutes after booting, although that varies.
