Hey. I'm having some trouble with my audio. I have the ASUS M5A78L LE motherboard with Realtek ALC887 8-Channel High Definition Audio and Logitech Ls21 7W 2.1 speakers and Windows 7 Ultimate 64.

When I built my system a year or so ago, I had the speakers plugged into the motherboard using the Realtek audio and was quite happy with the sound. I understand the speakers aren't exactly high-end. But they were good enough to fill my modest-sized room with clear, rich sound and deep base.

Some time after this, my power supply failed. After replacing it and getting my system back up and running. I realized that the audio was not the same. It was very quiet to the point that - on full volume - it was just about audible.

I thought it may be a driver issue, so I tried different versions. The driver that shipped on disk with the motherboard and the latest from the ASUS website, as well as the latest from the Realtek website. Non of these drivers changed anything.

I had a thought that perhaps the issue was with the speakers. So I plugged them into my LG IPS 224 monitor and used an AMD HDMI Audio driver. The audio was quite loud once again. More or less to the level it was originally using the motherboards sound card. So the speakers themselves are working.

I was more or less happy to use this method and just forget about the issue. But I began to notice that the audio was just not the same. On higher volumes and with more bass the sound becomes quite distorted and isn't really viable for music or gaming.

I would really like to get back the sound quality I had originally with the Realtek sound card/driver. But other than reinstalling Realtek drivers and tweaking Windows sound settings (none of which help) I really don't know what else to do.

Any theories, suggestions, help or advise would be greatly appreciated.
