Description of problem:
After installing RedHat 8.0 clean on my Dell Latitude C810 (which uses the ESS
Maestro 3i driver), there is a constant buzzing sound being immitted from the
speakers. It seems to correlate with the volume for the internal condensed
microphone. However, even if I mute the volume for everything (including the
microphone), the buzzing still exists. I've tried completely turning down the
volume as well. If I turn the volume for the microphone all the way up, the
buzzing becomes incredibly loud.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RedHat 8.0
2. Boot up the machine
3. There'll already be a faint buzzing sound
4. Turn up the volume for the microphone (via amixer or the GUI)
5. Now the sound is very loud
6. Turn down the volume, or even mute it...but the faint buzzing keeps going.
Actual Results: Constant, faint buzzing sound coming from the laptop speakers.
Expected Results: No buzzing sound.
This problem doesn't occur with RedHat 7.3, Mandrake 9.0, or Windows XP.
Dell Latitude C810, 512mb, 40gb HD, ESS Maestro 3i
