Pulseaudio + Bluetooth headset = Lags

Hello,

i have some problems using my bluetooth headset under archlinux.

1) After ~15min the sound suddenly stops
      - i tried to disable the suspend module as mentioned here: https://wiki.archlinux.org/index.php/Pu … y_problems
        but i didn't help at all. And my sound get's suspened while i'm listening to music
2) I often have long lags in the sound, this is not that much of a problem when listeing to music, but watching a movie like that just sucks
      - I noticed that this often happens when the headset is too far away for a short time, like when i'm e.g. in the bathroom and when i'm back, there is that lag. But it also happens while watching a movie

To me it seems like that whenever the headset is "unreachable" for just a second or so, that second is not skipped, but send to the headset when it's reachable again. That's where the lag comes from.
This also happens on a clean Fedora 17 installation.

The only solution i found so far is to switch off the headset and switch it on again.
I'm using gnome3 and pulseaudio with the standard configuration

Any help is appreciated.

Thanks in advance,

I just filed a bug report here https://bugs.freedesktop.org/show_bug.cgi?id=52364

Re: Pulseaudio + Bluetooth headset = Lags

i had the same issue 3 or 4 month ago.
I've abandoned it because i can't get it out.

Only a stuff: did u try with different headset? My chinese one has this kind of problem, but a Motorola one works fine.

Re: Pulseaudio + Bluetooth headset = Lags

I don't have any different headset to try it, but my headset is an "AKG K830BT". It works flawlessly with my android mobile and a ~20€ bluetooth transmitter. So i assume that somehow pulseaudio is to blame.

Here's the log of what happens when the sound stops:

To me this line looks interesting:

It seems like pulseaudio crashes completly and restarts afterwards.

Regards,

Robert

Re: Pulseaudio + Bluetooth headset = Lags

I just tested this again on the clean Fedora installation and i was unable to reproduce this. Fedora is using pulseaudio 1.1!

Maybe i'll try downgrading pulseaudio if it's possible...

Re: Pulseaudio + Bluetooth headset = Lags

I also have terrible lag with my Parrot Zik headphones. The problem seems to be similar to that of the OP. When I pair my headphones, they work fine, then after some time the sound starts to lag until the audio is very late (about 3-4 seconds, or so). Headphones and my Bluetooth device work fine on Windows machine. I also use the headphones with my Android phone, and they work very well.

Commenting load-module module-suspend-on-idle in /etc/pulse/default.pa doesn't seem to help.

Re: Pulseaudio + Bluetooth headset = Lags

Wow, the thread is from 2011 but still have no solution? I'm experiencing Vilius's problem with Jaybird Sprint bluetooth headset, - works fine on Android, but starts lagging with pulseaudio I guess (or whatever cause it)
