The sound you will go out of a computer system will never be better
than the sound you will get out and in from its hardware. With a real
intel HDA sound card, you can get a decent sound for an amateur or
audiophile studio if the mixer levels are set at 0dB (most audio
hardware, if not all, are optimized for that level, and this is
especially important to respect it with cheap hardware). That implies
the use of some external mixing gear to set the audio levels.

With an emulated hardware, the sound quality will depend on the quality
of the emulation. If the sampling rate is the same in the emulated OS
than in the host and the hardware (no added artefacts), it should not
really be a problem, assuming the computer is powerful enough to not
create glitches or xruns.

If you have a problem and you are not doing anything to fix it, you are
at the heart of the problem.
