Hello everybody, we have problem with quality of sound with pulseaudio used with freeswitch with portaudio modul, which gets worse(crackling) after random time (couple of hours). When we restart pulseaudio with our own script (in attachment pulseaudio-restart and pulseaudio-restore) everything gets back to normal. Everything is running on gentoo and installed like this: [I] media-sound/pulseaudio Available versions: [M]2.1-r1 [M]4.0 5.0-r2 (~)5.0-r3 {+X +alsa +asyncns avahi bluetooth +caps dbus doc equalizer +gdbm +glib gnome gtk ipv6 jack libsamplerate lirc neon +orc oss qt4 realtime ssl system-wide systemd tcpd test +udev +webrtc-aec xen zeroconf ABI_MIPS="n32 n64 o32" ABI_PPC="32 64" ABI_S390="32 64" ABI_X86="32 64 x32"} Installed versions: 5.0-r3(11:07:32 AM 10/21/2014)(X alsa asyncns bluetooth caps dbus equalizer gdbm glib gnome libsamplerate neon qt4 realtime ssl tcpd udev webrtc-aec -doc -gtk -ipv6 -jack -lirc -orc -oss -system-wide -systemd -test -xen -zeroconf ABI_MIPS="-n32 -n64 -o32" ABI_PPC="-32 -64" ABI_S390="-32 -64" ABI_X86="-32 -64 -x32") Homepage: http://www.pulseaudio.org/ Description: A networked sound server with an advanced plugin system Our hardware: Olimex A20 Cpu info: Processor : ARMv7 Processor rev 4 (v7l) processor : 0 BogoMIPS : 954.36 processor : 1 BogoMIPS : 957.64 Features : swp half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 4 Hardware : sun7i Revision : 0000 Serial : 0000000000000000 /etc/pulseaudio/daemon.conf ... in attachment /etc/pulse/default.pa ... in attachment users .pulse/default.pa ... in attachment pacmd info output ... in attachment We tried, to change aec method from speex to webrtc, only difference is, that cpu "eats" 5% less with speex. We tried also tsched=0, but it gets worse ... Does anybody know how to solve this and have clear sound all the time? Problem is with pulseaudio, that we know for sure, we have the same exactly setup on 6 pc's in different locations. Thank you!
