Let me check point 1 when I go to that home. What should I do? enable or disable that?
Unless you actively want to have two sound cards active, disable the SB emulation in BIOS if using a sound card.
About point 2, as I can remember integrated audio was commonly worse than dedicated audio, and do exist drivers for w95 or 3.11 and DOS for the integrated audio of those motherboards?
'Integrated audio' can mean a lot of things. These specific boards have Via 686 integrated audio with legacy SB emulation, which is pretty unique. That emulation does what the name suggests: emulates a Sound Blaster. So it works in DOS and Windows 3.1 like a Sound Blaster, more specifically like a Sound Blaster Pro 2.0. In DOS games, select that as your sound card, in Windows 3.1 install the SBPro 2.0 driver.
There's a topic here about it: VIA 686B AC'97 audio works really well in DOS (SB Pro stereo + OPL3 emulation!)
Quote from it (that corresponds to my experiences):
I've found the onboard sound on these to be highly compatible with DOS stuff and very easy to set up.
You just set resources in BIOS and then run a relatively simple TSR, either VIAAUDIO.COM or VIASBCFFG.COM (and if you want FM, VIAFMTSR.COM). They have no specific memory type requirements.
The FM synth emulation isn't good, but there are worse - and you have one example on your PCI card.
All in all not perfect (TSR needed - even if relatively well-behaved, FM not good), a random ISA sound card with hardware SBPro2.0 support would probably be better - but that's not what you're comparing it to.
Note that this is specific to the integrated Via 686 audio, this does not apply to other integrated audio solutions on older or newer Via chipsets or chipsets from any other vendor.
On the other side you have the SB128, which is one of the least interesting PCI sound solutions out there. To work in DOS it needs nasty TSR drivers that require EMM386 (a problem for some games) and eat memory. It also has pathetically bad FM synth (for "Ad Lib" music). It does however have a good MIDI wavetable synth that's usable under DOS if you can spare enough EMS for it.
Here's info https://www.dosdays.co.uk/topics/audiopci.php
(almost all SoundBlaster PCI cards are based on the Ensoniq AudioPCI, regardless of whether they are called "64" or "128")
