I think "good quality sound" can be produced by most onboard audio controllers manufactured since the mid 1990's. All a sound card might offer you is better connection options (optical) and perhaps some amplification. HDMI doesn't have much impact on the quality of audio,either.. it is, after all, just a connection standard. Audio will travel along the HDMI cable to the TV, and it will output to the TV's internal speakers (which is generally good enough for everyday viewing). If you want that audio to sound better (5.1 or something like that), then you need to move that audio signal from the TV to a receiver that would be capable of decoding that signal.
I have two HTPC's. My main system was built using the MSI Media Live Diva 5.1 board (which uses a separate 5.1 channel 100 watt/channel amplifier card). I output audio directly to my home theater speakers. The other HTPC is a mini-itx system. I designed it with a minimum footprint for my living room. Most of the time, the audio from the TV is used (basic TV watching), but I do have a Bose Cinemate 2.1 amplifier. It's connected to the TV via optical cable. The Bose rivals my 5.1 system for Music and DVD playback. On top of all that, I also use DFX audio enhancer (http://www.fxsound.com/dfx/index.php
) on both systems.Edited by ajkrishock - 2/4/13 at 11:22am
