Hello guys.
I finally can report some interesting news.
Now audio stopped working - still, the system didn't panic. So I consider this a good good point.
My system is alive and I can keep it alive indefinitely, clearly if hardware doesn't break and/or other events out of my control cause an interruption.
In my dmesg, the following messages started to appear:
snd_hda_intel 0000:00:1b.0: azx_get_response timeout, switching to polling mode: last cmd=0x020c0000
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x1f0e00. -5
And they appear apparently when the driver tries to send new commands to the device, but this is only my impression.
Let me know what I could do to report on what's happening. My system is acually running with kdump active, so in case I may also invoke the crash sysrq action and send back results.
sending alsa-info as attachment.
Thank you for everything guys, and forthe patience.
thank you Takashi.

Sometimes it's my impression the beep is not emitted. but I may be wrong. If I determine it, I'll report back.
But the system is stable so far, and I can't find other messages in the dmesg.
OK, thanks. The hackish patch can't be kept / merged to the upstream
code, of course. Instead, try the patch below and pass single_cmd=0
option. This will disallow fallback like the hack patch.

From: Takashi Iwai <tiwai@xxxxxxx>
Subject: [PATCH] ALSA: hda - Make single_cmd option to stop the fallback
mechanism
HD-audio driver has a mechanism to fall back to the single cmd mode as
a last resort if the CORB/RIRB communication goes wrong even after
switching to the polling mode. The switching has worked in the past
well, but Enrico Mioso reported that his system crashes when this
happens.
Although the actual cause of the crash isn't still fully analyzed yet,
it'd be in anyway good to provide an option to turn off the fallback
mode. Now this patch extends the behavior of the existing single_cmd
option for that. Namely,
- The option is changed from bool to bint.
- As default, it is the mode allowing the fallback to single cmd.
- Once when either true/false value is given to the option, the driver
explicitly turns on/off the single cmd mode, but without the
fallback.
That is, if you want to disable the fallback, just pass single_cmd=0
option. Passing single_cmd=1 will keep working like before.
