That's weird, pulseaudio gets your card even before "alsactl init".
Now, all the following hints are to be tried without issuing your workaround - alsactl init!
The IDLE/SUSPENDED state is controlled from /etc/pulse/default.pa in the section:
Code:
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
and as far as I understand it, it suspends the sink if IDLE for too long and that could get you some artifacts (pops/clicks) when activating it again - that's starting to play some sound, or, it could take some time to reactivate the sink(output). Just to rule out the last scenario, you can try commenting that line in /etc/pulse/default.pa and bounce pulseaudio:
Code:
/usr/bin/pulseaudio -k
/usr/bin/pulseaudio -D
Given that you experience the reported issue on a laptop I'd suggest to investigate the PM state of the sound card. Some lecture:
https://www.kernel.org/doc/html/v4.1...powersave.html
https://01.org/linuxgraphics/gfx-doc...dio/notes.html
https://wiki.gentoo.org/wiki/Power_management/Soundcard
Try loading the snd-hda-intel driver with:
Code:
options snd-hda-intel power_save=0
in /etc/modprobe.d/snd-hda-intel.conf
One last hint, I just stumbled upon this Ubuntu HowTo related to the snd-hda-intel driver:
https://help.ubuntu.com/community/HdaIntelSoundHowto
and I'd suggest to read the "Manually Specify Module Parameters" chapter and try loading the driver with:
Code:
options snd-hda-intel model=basic
instead of auto, like in the "Example" section, or, go on and play with the probe_mask.
There's also an option to specify the exact model of your card/hardware, but your Panasonic laptop is apparently not in the list:

Well, you could try all of them...just kidding
I wish I could help more but since I don't own your HW, I'm limited to speculation.
