--- Comment #91 from Alessandro Ferri <[email protected]> --- (In reply to Raymond from comment #88) > http://lists.freedesktop.org/archives/pulseaudio-discuss/2014-October/022019. > html > > seem you may need to set fragment time to 80ms Hi Raymond, I made the changes to the set up of /etc/pulse/daemon.con that you have required. There are not differences in the use of cpu by pulseaudio, following the results. I will attach the file daemon.conf. pi@raspberrypi ~ $ uname -a Linux raspberrypi 3.12.30+ #717 PREEMPT Fri Oct 17 18:46:31 BST 2014 armv6l GNU/Linux pi@raspberrypi ~ $ top top - 10:10:52 up 2 min, 2 users, load average: 2.06, 0.87, 0.33 Tasks: 92 total, 1 running, 91 sleeping, 0 stopped, 0 zombie %Cpu(s): 46.8 us, 28.9 sy, 0.0 ni, 20.0 id, 0.0 wa, 0.0 hi, 4.3 si, 0.0 st KiB Mem: 447856 total, 137784 used, 310072 free, 14892 buffers KiB Swap: 102396 total, 0 used, 102396 free, 68368 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2335 pulse 9 -11 87984 4836 3532 S 56.5 1.1 0:25.69 pulseaudio 2401 pi 20 0 115m 3816 2420 S 17.5 0.9 0:07.07 shairport 2579 root 20 0 22292 11m 4844 S 1.6 2.6 0:03.42 Xorg 2757 pi 20 0 4668 1380 1036 R 1.3 0.3 0:00.55 top Like I mentioned I have noticed a slight improvement just by adding the following line to /etc/pulse/system.pa: load-module module-alsa-card device_id=0 tsched=true tsched_buffer_size=256072 tsched_buffer_watermark=120268 This is the results: pi@raspberrypi ~ $ top top - 10:05:31 up 3 min, 2 users, load average: 1.01, 0.55, 0.23 Tasks: 93 total, 2 running, 91 sleeping, 0 stopped, 0 zombie %Cpu(s): 41.1 us, 22.8 sy, 0.0 ni, 33.8 id, 0.0 wa, 0.0 hi, 2.3 si, 0.0 st KiB Mem: 447856 total, 137228 used, 310628 free, 14912 buffers KiB Swap: 102396 total, 0 used, 102396 free, 68012 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2404 pi 20 0 150m 4764 3632 R 40.2 1.1 0:21.11 pulseaudio 2400 pi 20 0 115m 3988 2588 S 18.4 0.9 0:07.99 shairport 2675 root 20 0 22004 11m 4844 S 1.6 2.5 0:02.42 Xorg 2766 pi 20 0 4672 1380 1036 R 1.6 0.3 0:00.53 top ut changing the values of tsched_buffer_size= tsched_buffer_watermark= there are no differences -- You are receiving this mail because: You are the QA Contact for the bug.
