Question about Dell Dimension 9150 (DIM915MIN) PC Desktop
dell dimension 9150, about 3 years old with SB audigy 2 ZS soundcard.
After the computer has been on for some time (never the same amount of time, but lets say between 10 & 30 mins) the sound volume will suddenly change, either quieter or louder, its choice! a few seconds later it will change back again, and so on. It only seems to affect the speaker system (dell 5.1 system); if you are on headset, it does not happen. I have re-seated the sound card and re-installed the soundcard driver, both without any success. I suspect it is the soundcard failing, but would that not also affect the headphones?
No, the headphone output is designed for 2 speaker output. Just recently I had a customer who had no sound coming from the desktop speakers yet the headphones worked just fine.
I believe that your model has a sound circuit integrated into the motherboard. It may have a “plastic cap” covering the audio ports (next to the USB ports). If you remove the sound card and enable the integrated audio in the BIOS, you can check to see if the sound card is actually the problem.
