This is probably an issue with the timing logic in the a52 ALSA
backend. pavucontrol sets rather short latency settings on all devices
to be able to show the PCM monitoring meters that closely reflect what
you actually hear. These lower latency settings probably break the a52
backend.

Please note that Fedora does not ship that module due to patent
issues, and hence I have never tested if it actually works. I wrote
the a52 logic in PA without ever having tested it.

It would probably be a good idea to include the a52 logic directly in
the PA plugin to fix all the timing issues, instead of relying on ALSA
for that. But uh, given the broken patent situation this is unlikely
to happen anytime soon. Sorry.

I'm afraid that this is a pulseaudio list, so this is a little 
off-topic. You'll no doubt have better luck on a jack mailing list :)

PA Startup problem on Acer Aspire One

Strange issue.. my Acer Aspire One is having issues since I installed pulseaudio on it.. I think they might
be related to bootup speed, since this model has a rather slow SSD from which it boots. I'm running PA 0.9.15

Essentially, if I start PA using the 'normal' method (i.e. just install it and let the scripts do what they
are supposed to) then I get no audio. I can start pavucontrol and I can see activity in the vu meters for the
applications, but there is no activity on the vu meter for the output (Intel HDA). I also can't play
anything using direct ALSA output in an application, because something (PA presumably) has control of
the sound card, although module-suspend-on-idle is loaded.

If I kill pulseaudio and start it again from the command line, it all works correctly.

I have a suspicion that it might be due to the slow bootup and perhaps something to do with suspend on idle. Can
I disable suspend on idle somehow to test this theory (I couldn't find it in default.pa)? Anyone else have
any other ideas?

Thanks,

Mark

I've also discovered that once a PA is in cpu-hogging mode (i.e. after
resuming an app., like rhythmbox), simply pausing whatever is driving it
(i.e. rhythmbox) and waiting for PA to settle down then resuming (i.e.
rhythmbox again) and PA will be again operating normally.

Maybe this helps trigger an idea/thought.

not allowed to configure local sound server

Hello,

On a Debian Testing machine, I have noticed that I am no longer allowed
to configure local sound server in pulseaudio device chooser (got by
padevchooser), presumably after some relevant upgrade in the recent few
weeks. The option in the various tabs in the chooser's interface
are all grayed out. I have seen the same problem in another Testing machine.

In a Debian Unstable machine, however, the options are allowed to be
changed, as expected.

Anybody else facing the same problem? Or know how to fix this?

I belong to pulse-access and pulse-rt groups in addition to audio and video.

This is on kernel 2.6.26-2-686 and I also have:
$> dpkg -l *pulse* | grep ^i | gawk '{print $2 "  " $3}'
gstreamer0.10-pulseaudio  0.10.15-1
libpulse-browse0  0.9.15-2
libpulse-mainloop-glib0  0.9.15-2
libpulse0  0.9.15-2
pulseaudio  0.9.15-2
pulseaudio-esound-compat  0.9.15-2
pulseaudio-module-gconf  0.9.15-2
pulseaudio-module-hal  0.9.15-2
pulseaudio-module-x11  0.9.15-2
pulseaudio-module-zeroconf  0.9.15-2
pulseaudio-utils  0.9.15-2

Thanks.

Even if pulse suspends itself, it should be able to unsuspend OK unless 
something has snuck in and grabbed the device.

When it's in this locked state, the output of "pacmd list-sinks" will 
confirm if it's in the suspended state and you should be able to issue a 
"pacmd suspend-sink 0 false" to unsuspend sink with index 0. If it is 
locked into a suspend state, this should try and unsuspend it.

You can also try hitting the mute button twice in pavucontrol to see if 
it is another occurrence of the infamous "undetected mute on startup bug."

Look again ;)

My default.pa has:
### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle
