you have to ask the distribution maintainer how to test the latest alsa-driver without upgrading the kernel.
it look like the driver is not installed correctly
!!Aplay/Arecord output !!------------
APLAY
aplay: device_list:240: no soundcards found...
ARECORD
arecord: device_list:240: no soundcards found...
!!Amixer output !!-------------
!!-------Mixer controls for card 0 [SB]
Invalid card number. Usage: amixer <options> [command]
Most likely you will need this patch
cb34c207af4944e9c93e2b462e351430f15daad6
so that the driver do not create "smart5.1" control since blue jack may need to retask as side according to the user manual
ALSA: hda - VIA: Fix Smart5.1 isn't useful for 6 audio jacks motherboard.
Lastly, do I need to enable debug? (that is, is it required for better alsa-info output?)
The driver print debug messages in system log , you are able to know which [Audio Output] is used when switch "Independent HP" on/off or retask blue jack as output
For now, below I'm posting alsa-info.sh output for current configuration and for kernel 2.6.33.2 (with working sound), hoping this can help for comparison.
Post the output of alsa-info.sh
What is the model of your computer (desktop/notebook) ?
Mine is a home-build desktop with an Asrock motherboard (I don't know of any notebook with asrock MoBo), model '890GX Extreme3', with integrated graphics (Radeon HD4290) and audio (via vt2020 codec and ati hdmi), NB AMD 890GX, SB850;
How many audio jacks ?
Rear panel: 5 jacks for 7.1 channels audio + 1 Optical SPDIF OUT port On board: front panel audio header for ac97/hd audio (connectors for mic, left, right -
Refer to page 12 of 890GX Extreme3 's user manual
TABLE for Audio Output Connection
Blue jack is re-tasked for "Side" channel to support 8 channels
"hda-codec: no NID for mapping control Independent HP:0:0".
Node 0x28 HP is connected to 0x34 through 0x1b
[Audio Output] 0x0c has the "Headphone Volume" control
As "Line in" can only be connected to 0x0c
so the fix mainly depend on whether 0x0b can be used or not
if vt2020 is as same as vt1718s, you need to find a correct nid in the function side_mute_channel() for update_side_mute_status() which mute/unmute side channel when independent HP Is "ON"/"OFF"

Node 0x21 only has 5 connections instead of 6
Seem no "Stereo Mix" , 0x28 is HP and only 0x2c, 0x2b and 0x29 are input sources and the other must be muted
node 0x2a "Line Playback Switch" have to be muted and write-protect whenever blue jack is retask
need to modify vt1718S_auto_create_analog_input_ctls()

I'm not sure if that's for supporting 2 independent mono jacks, one stereo (headset) jack or both cases,

Multistreaming allows you to listen to two different audio sources on two different speaker sets. For example, you can listen to one audio source through the back panel speakers and a second audio source through front panel headphones or speakers.
In page 13,
To enable Multi-Streaming function, you need to connect a front panel audio cable to the front panel audio header,
I don't know neither ac97, nor hd audio specifications) + header for 1 hdmi_spdif out (to be connected to a discrete vga with hdmi capabilities)

How to Identify your Front Panel Audio Solution Codec
*You can also physically check the audio cable of the front panel audio solution. If there is a cable connected to Pin 4, you have an HD Audio module; if there is no cable to Pin 4, you have an AC97 module.
