[Bug 485488] Re: Applications routed through the pulse pcm alsa-plugin crackle/die quickly

2010-02-06 Thread Jamie Nicholson
I installed the new pulsaudio and alsa and it made my glitchy sound even worse.
Have been using mangler and HoN concurrently and HoN completely dropped off 
then mangler sometimes following suit.

Changed my sound settings for both applications so they used the
internal audio and touch wood everything is working.

Using David's alsa-plugins package (libasound2-plugins), playback works
but recording still is cracked when using TeamSpeak 3 beta 12. I set the
Capture Mode to ALSA and Capture Device to 'default'. I then changed the
capture (and playback) device via pavucontrol to the desired device.

Lol, I feel stupid |:( Installing the new pulsaudio package which was
released today (pulseaudio 1:0.0.19-0ubuntu4.1) and rebooting has fixed
the problem.

Many thanks :)

I'm trying this out in hopes of a fix too. I hope everyone realizes that
the many layers of complexity that exist now on linux audio world are
evidently making everything increasingly difficult to mantain... since
pulseaudio has been made default in ubuntu, i've been having problems
with it on every machine i have.. from PA constantly crashing and
leaving me with no sound, to crazy 100% CPU usage peaks, and now this.
Yes I know those bugs are now fixed, but it can't be denied that they
did happen due to having an extra layer! I used to install OSS4 to solve
all my issues, but now Gnome in ubuntu 9.10 does not even support that
(mixers just stop working).

2010-01-10 Thread WhyteHorse
I tried this PPA but I still get sound dying in GLest and a 2 sec delay
when launching a music file in totem. It only has the delay the first
time I run it after booting up. Perhaps my issue is with the Totem Movie
Player 2.28.2 using GStreamer 0.10.25 during initialization because if I
close the app and then play another song it has no delay... Perhaps pre-
cache is not working as designed or my system is hosed?

I can't tell if the system is using less cpu now but I just upgraded to
kernel 2.6.31-17-generic and the system now balances cpus properly and
screams along even if I'm playing music, flash, etc.

Overall can't complain except for GLest not playing sounds after about
2min and playing the snap-crackle-pop just before dying followed by
slight crackles every time a sound event is generated.

and GLest - OpenAL - Pulse  - none of those paths should include the
ALSA plugin, so they are not affected by this patch.

2010-01-07 Thread ekilfoil
I'm the Mangler developer that first noticed the problem in the original
ticket.

FWIW, something definitely changed between 9.04 and 9.10.  The PA ALSA
plugin used to deliver audio at a fairly low latency (low enough that
the default worked for our needs).  The newer version of PulseAudio
increased this latency significantly (from about 0.1 seconds to about 2
seconds or so) in the simple API.

I don't know if it was intentional or not... it could very easily be a
power saving measure to reduce CPU wakeups by the pulse daemon, but the
result is horrible for ALSA apps that are expecting low latency.

I think there's two separate problems being described in this bug
though.  One is latency problems and the other is sound dropping (buffer
problems).  They're probably related, but are two different issues.

2010-01-07 Thread ekilfoil
Two other things:

1) PulseAudio's alsa plugin should honor the requested latency from the call to 
snd_pcm_set_params() by setting pa_buffer_attr.fragsize accordingly.
2) PulseAudio's alsa plugin should honor ALSA calls to snd_pcm_drain() -- which 
I think are most likely the cause of the audio cutoff when combined with the 
high latency.

2010-01-07 Thread David Henningsson
Well, here is something to try out. I'll fix something more appropriate
(git-send-email, debdiff, etc) in the next few days, right now I'm a bit
to tired for the formalities. But I hope these three fixes should
improve the situation.

1) 
+   /* Prevent accidental overrun of the fake ringbuffer */
+   if (size = pcm-buffer_attr.tlength) 
+   size = pcm-buffer_attr.tlength-1;

This cured a hang I could sometimes reproduce while recovering from an
xrun.

2)
+writebytes = size * pcm-frame_size;
+   ret = pa_stream_write(pcm-stream, buf, writebytes, NULL, 0, 0);
+pcm-last_size -= writebytes;

This updates the hw_ptr variable correctly, which fixed some continous
xruns for me as well as reduced CPU usage.

3)
+/* Reset faked buffer */
+pcm-last_size = 0;
+pcm-ptr = 0;
+update_ptr(pcm);

Before prepare is called the ioplug interface resets its pointers, so we
should do the same. No real difference in experience from this one, it
just seems reasonable.

The tsched=0 trick made it even worse for me... I can't use linphone
(via alsa via pulseaudio) anymore since upgrading to Karmic.

The sound problems could be related to the reduced timer frequency of
the Karmic kernel from 250 Hz to 100 Hz. Is there some competent person
to assess this?

Raising the timer frequency seems to solve a completely different bug,
which appeared since Karmic: virtualisation performance has degraded
drastically. See http://www.virtualbox.org/ticket/5501#comment:21

2009-11-26 Thread Vadim Peretokin
Any progress on this?

** Description changed:

  Binary package hint: pulseaudio
  
  I'm assuming that ubuntu-bug adds all the technical information about my
  system, so I'll skip on that.
  
  In short, on Jaunty - sound from game was fine on default settings.
  
  On Karmic - sound 'crackles' at first, and then eventually just dies. No
  sound coming from game at all. Checking pavucontrol, it's not emitting
  any sound. Nothing changed with the game. The game will also hang on
  exit until I kill the games output stream in pavucontrol. (the hang on
  exit is caused by snd_pcm_writei hanging (gets stuck in a blocking poll
  in libasound))
  
  Now, nobody really knows what's going on, so I'll just dump all that I
  know at first.
  
  The problem is somewhere in the alsa-PA layer.
  
  Changing the games sound buffer to be 4*4096 fixed the problem for me
  (what changes is that snd_pcm_hw_params_set_buffer_size_near gets
  passed a larger value)
  
  It's affecting certain HDA Intel sound chipsets (not all HDA intel).
  
  Mangler project says that the default latency changed:
  http://www.mangler.org/2009/10/two-major-fixes-today/
  
  There are many people on the games forum with this issue, although I
  can't give direct links as its in closed beta. But here are various
  things people have posted, that worked for some, and not for others:
