Ensoniq 1370 On-board Gateway 2000

Postby Formulator » 2019-4-10 @ 00:49

Cleaned up this nice Gateway P5-200 this past weekend. No problems except for on-board sound, quality is terrible, high noise floor and sounds like a telephone speaker. Any possible fixes or do I need to go sound card? Also can't disable on-board sound in BIOS either.

Funny i have the same (almost) exact machine but mine has a discrete sound card (also with an ensoniq chipset)
I have no clue what I'm doing! If you want to watch me fumble through all my retro projects, you can watch here: https://www.youtube.com/user/MrDavejustdave

I should have phrased this better. Everything coming from the output has a very limited frequency range, audio, MIDI, and CD. I have not yet done a frequency analysis on the output but likely will do that at some point.

As an experiment I installed a discrete ES1370 PCI card and had no issues with frequency output. However, since the onboard audio cannot be disabled as far it did cause some redundancies in device manager.

I do wonder if the onboard PCI has a deliberately limited frequency range or if it requires a different/specific driver for the onboard variant.
