But I've owned PC and such repair shops.
To test I use a Live bootable OS from CD/USB/DVD. I have a collection today and here's my old advice recently -> http://tips.oncomputers.info/archives2004/0401/2004-Jan-11.htm
On Amazon there are best seller USB Audio dongles that are under 10 bucks. That's my usual fix if the hardware fails further testing.
Lost the sound from my speakers overnight, tried a headset in both speaker jacks on the rear of my PC with no sound. Never heard of a sound card failing. Any info/suggestions appreciated.
