Hi, I had no time to test your first patch (this one which check if irq 
handler is called), I've only tested it for a while (working on MSI turned 
on, sometimes hard locks my laptop).

I also have similiar problems with automute, and non-linear master volume 

Without automute patch, automute works from time to time. With your patch 
applied to latest git it works all the time, until the recording breaks. When 
it happens I have sound only in headphones, but not in internal speaker. 
Pluging and unpluging HP doesn't help, only reloading hda-intel fixes 
Assuming, your automute patch is ok, but it helps me only until mic breaks.

Without ad1981-hp-master-amp-fix muting (muting=disabling it, not making it's 
value equal 0) "Master" and "PCM" control works ok. Decrementing Master and 
PCM controls to 0 is possible, but after that I can hear very quiet output 
from internal speakers.
With your patch (ad1981-hp-master-amp-fix) applied to latest git I can't 
decrement Master control to 0 (I can do that with PCM, but behavior is same 
as described upper). I can only decrement it to value 3, and when I press 
down key (in alsamixer) to step to lower level of loudness, it's switching to 
value 103. When Master has 103 value I can hear very quiet output from 
internal speakers and HP (if plugged).

I hope you understand my english ;)

PS. I will test your irq_handler_check patch today, and I will send results
