Great, thanks Oleksij,
I tried this on an ACER AC700 which also has the ALC269VB and could
not get anything like this to happen. So I'm sorry to keep bothering
you for more information. I attached the alsa-info.sh output, if you
see any interesting differences let me know.
>From the output it looks like something is opening the driver about
three times a second, do you know what is doing that? It appears to
be doing what it should be in this case, although it is a little hard
to tell. If you could strace the process doing all the opens that
might provide some good info.
Thanks again for the help.
