Thanks Oleksij,
I didn't get much from that though. What is your powersave timeout set to?
I do not know, it should be some default value.
If you have time could you try adding the following and send me the output, I have two guesses about where it is spending it's time (no guesses about why yet though). I've got a couple of systems with a 269, I'll try to get some tests run on those tomorrow.
result is attached.
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. Dylan
Ok, i did some more testing compared the difference between battery and non-battery mode.
first of all on non-battery mode, this part of code is not executed. I have no messages about "power_up cancel sync". Then i found some difference in syslog.
Here is what pulse audio say if i reproduce this issue: [pulseaudio] module-alsa-card.c: Failed to open hctl/mixer for jack detection
Interesting, I'll try to get pulseaudio installed on my system to test tomorrow. Does it give any more info if you turn up the verbosity? (set log-level to debug in /etc/pulse/daemon.conf)
