[Bug 273742] Re: Pulseaudio over wifi stutters horribly
I figured out that Network Manager is what causes the scanning, and that can be stopped by setting the BSSID of the connection in the Network Manager settings. (In KDE there's a "Select" button next to the BSSID field that fills this in automatically if you're already connected to your AP.) Since the BSSID is set, you won't be roaming from one AP to another, so NM doesn't scan for other APs with the same SSID. So I set my BSSID and that has stopped the scans, which I think happened every 120 seconds (according to the NM source). That has nearly completely fixed the stuttering. Any stuttering that remains is much less frequent and less severe; I'm not sure if it's network-related.

[Bug 273742] Re: Pulseaudio over wifi stutters horribly
For a few weeks I've been using PulseAudio network tunneling over wifi. I've noticed that on a very regular interval the audio stutters for a few seconds. I've been watching network traffic in KSysGuard, and I noticed that the transmit rate is usually about 200 KB/sec, but when the audio stutters, the transfer rate drops slightly. When that's the only thing going on on my network, I can observe this happening at a completely regular interval. I finally figured out that it's caused by my laptop's wireless card scanning for other networks. I can make it stutter in exactly the same way on command by running "iwlist scan". My laptop has an "Intel Corporation PRO/Wireless 4965 AG" network card, and it uses the iwl4965 driver. Now my laptop very rarely moves anywhere, and it is always on my home wifi network, so I don't need it to scan for other networks. If I could simply disable scanning on my laptop, it wouldn't stutter anymore. Of course, more buffering in PulseAudio would help a little, but I think all it would do is cause it to stutter a bit less often. Eventually the stuttering would cause the buffer to empty, because it can't fill faster than audio is being played. So it could stutter less often, for a longer period of time, but it would still end up stuttering. I've been googling around, trying to find a way to adjust the scan interval, but I haven't found anything yet. I'm not sure if it's controlled by wpa_supplicant or the driver. I've also seen that some cards seem to support "background scanning" and others "progressive scanning", and I don't know if one of those would mitigate it, or if my card already does one of them. Anyway, for anyone else who is having stuttering, if you're on wireless, one cause of it is almost surely the scan interval. Find a way to fix that and you may solve it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/273742 Title: Pulseaudio over wifi stutters horribly To manage notifications about this bug go to: https://bugs.launchpad.net/pulseaudio/+bug/273742/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 273742] Re: Pulseaudio over wifi stutters horribly
i have raring on both machines, the desktop has a wired connection and a laptop has wifi-n the audio i still bad, every 3-10 seconds i hear pauses. WHen using wired connection on a laptop - works perfectly. My wifi pulls 80mbit/s according to iperf, while pulseaudio uses 3093.7 kbits, according to iptraf. Is there a way to increase the pulseaudi default buffering?

[Bug 273742] Re: Pulseaudio over wifi stutters horribly
No need for me to add anything to this bug as we all know it exists. Wifi is laggy, cable good. I would just like to add that this network sound is a killer feature of pulseaudio, and therefore also of ubuntu. There are so many use cases where this feature is useable by non-technical end users. Most people have a stationary computer connected to their stereo and use a laptop or other device around the area. Sending sound output to the stereo is in many cases a great convenience. I propose that this feature is a reason for many people who don't see a reason to shift from Windows or OSX to consider ubuntu, but as the situation is now there are a few issues that needs to be addressed: 1) Stability. For some reason my 10.04 installation stopped being able to play back sound it recieves from network. I believe this to be fixed with later installations. 2) Lag. Sound needs to play instantly, or almost instantly. I know that this an inherent design limitation of doing this over wireless, but there is a lag of more than what the latency of the network can account for. Sometimes 1-10 seconds. 3) Integration into the desktop. If issue 1 and 2 gets fixed to a point where it would be considered acceptable by end-users desktop integration should be addressed. For example, people need to be aware of this feature. It needs to be integrated into applications that ship with ubuntu. For example Totem could have a feature to compensate for the network lag if it was aware that it was redirecting sound over the network. Banshee could have a button next to the volume which could be pressed and sound would play over the network instead leaving other applications sounds still playing on the local sound card, for example system sounds, totem video, flash plugin etc. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/273742 Title: Pulseaudio over wifi stutters horribly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 273742] Re: Pulseaudio over wifi stutters horribly
Same here, it still persists in 11.04 although it seems to be happening less then before. I think it needs some buffering but this would mean a delay which will ruin any use where sound is used as reaction on something you did. For music (which is my main use) it would be fine though. Maybe an idea to add some buffering options to the pulseaudio network stack? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/273742 Title: Pulseaudio over wifi stutters horribly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have the same issue on 11.04 when playing audio from my netbook through my laptop using PulseAudio. The audio is very glitchy, playing at random. Sometimes it will play for 10-30 seconds just fine and then it goes into 10 seconds of choppiness.
