Page 11 - Onboard Sound (RMAA 6.2.3) Analyzation
Jetway does not talk too much about the onboard VIA VT1705 6-Channel HD audio codec, and there was no information to be found on VIA's website either. But let's see how well it performs in our RightMark Audio Analyzer tests.
Test Information:
Testing device: Speakers (VIA High Definition Audio)
Sampling mode: 16-bit, 48 kHz
