Raymond, I can't seem to locate that script.

Thank you, see attached script output.
Do your VIA 8237/ens1371 has any digital output/input ?
That I can't answer
Do your motherboard/sound card has optical/coaxial spdif ?
Not that I can see.

Module snd-via82xx ------------------
Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) channels as the first PCM. On these channels, up to 4 streams can be played at the same time, and the controller can perform sample rate conversion with separate rates for each channel. As default (dxs_support = 0), 48k fixed rate is chosen except for the known devices since the output is often noisy except for 48k on some mother boards due to the bug of BIOS. Please try once dxs_support=5 and if it works on other sample rates (e.g. 44.1kHz of mp3 playback), please let us know the PCI subsystem vendor/device id's (output of "lspci -nv"). If dxs_support=5 does not work, try dxs_support=4; if it doesn't work too, try dxs_support=1. (dxs_support=1 is usually for old motherboards. The correct implemented board should work with 4 or 5.) If it still doesn't work and the default setting is ok, dxs_support=3 is the right choice. If the default setting doesn't work at all, try dxs_support=2 to disable the DXS channels. In any cases, please let us know the result and the subsystem vendor/device ids. See "Links and Addresses" below.
