[Bug 1453282] Re: [Neither headphones nor speakers are displayed under "All Settings"->Sound, VIA VT1718S, Green Headphone Out, Front] No sound at all

 

<sigh>So do you think the BIOS is the root cause? It is ~5 years old and
I've flashed the latest firmware some years back and I'm sure they won't
be supporting any more changes.

I haven't really had issues in Vista but knew in time I'd likely shift
to Linux.

Is there a way to find out what hardware is surely compatible prior to purchasing it (no bios, acpi, usb, ... flaws)?
I am aware of "Desktop Hardware Compatibility List" (http://ubuntuforums.org/showthread.php?t=361236), but can't trust any of it.
I could have posted that mine was compatible since everything would (seem to) work using Ubuntu Live or even right after the install, but there would be issues below the surface that could only be found in the log or by putting the system to sleep/resume, and logs aren't posted on that thread.

"When" I upgrade my hardware, I'd like to know the logs will be clean of
any errors due to hardware misprogramming.
