hi list, i compiled pulseaudio 4 onto linux mint 13 amd-64 with a basic configure according to below first clues from syslog occurs after each system startup: *Aug 6 14:13:53 tarantino pulseaudio[3518]: [pulseaudio] authkey.c: Failed to open cookie file '/home/fulano/.config/pulse/cookie': No such file or directory *Aug 6 14:13:53 tarantino pulseaudio[3518]: [pulseaudio] authkey.c: Failed to load authorization key '/home/fulano/.config/pulse/cookie': No such file or directory *Aug 6 02:58:53 tarantino pulseaudio[3632]: [alsa-sink-ca0106] alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! *Aug 6 02:58:53 tarantino pulseaudio[3632]: [alsa-sink-ca0106] alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_ca0106'. Please report this issue to the ALSA developers. *Aug 6 02:58:53 tarantino pulseaudio[3632]: [alsa-sink-ca0106] alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. i have a creative soundblaster audigy value/SE 7.1 pci card (yep, its a fake 24/96 oldie) essentially ive tried solving this my self for a while but i dont have enough experience in the sound arena the only playback issues i have are with internet flash videos and 5.1, 7.1 streams (including DTS) which both play with an intermittent stuttering or tapping sound - the stuttering or tapping doesn't occur during times of silence or reduced volume/quieter times - seems to occur at peaks conversely, playing mp3, lame, wma, flac 24/96, regular h264 stereo videos, etc, are ok i haven't debugged this for a while but from memory i tried altering fragment values any initial starting advice would be really appreciated or if need be i could pass on some terminal output whilst playing thank you ---{ pulseaudio 4.0 }--- prefix: /usr/local sysconfdir: ${prefix}/etc localstatedir: ${prefix}/var modlibexecdir: ${exec_prefix}/lib/pulse-4.0/modules System Runtime Path: /usr/local/var/run/pulse System State Path: /usr/local/var/lib/pulse System Config Path: /usr/local/var/lib/pulse Compiler: gcc -std=gnu99 CFLAGS: -g -O2 -Wall -W -Wextra -pipe -Wno-long-long -Wno-overlength-strings -Wunsafe-loop-optimizations -Wundef -Wformat=2 -Wlogical-op -Wsign-compare -Wformat-security -Wmissing-include-dirs -Wformat-nonliteral -Wpointer-arith -Winit-self -Wdeclaration-after-statement -Wfloat-equal -Wmissing-prototypes -Wredundant-decls -Wmissing-declarations -Wmissing-noreturn -Wshadow -Wendif-labels -Wcast-align -Wstrict-aliasing -Wwrite-strings -Wno-unused-parameter -ffast-math -Wp,-D_FORTIFY_SOURCE=2 -fno-common -fdiagnostics-show-option LIBS: -lcap -lpthread -lrt -ldl -lm Enable X11: no Enable OSS Output: yes Enable OSS Wrapper: yes Enable EsounD: yes Enable Alsa: yes Enable CoreAudio: no Enable Solaris: no Enable WaveOut: no Enable GLib 2.0: yes Enable Gtk+ 3.0: no Enable GConf: no Enable Avahi: yes Enable Jack: yes Enable Async DNS: no Enable LIRC: yes Enable Xen PV driver: no Enable D-Bus: yes Enable BlueZ: no Enable udev: yes Enable HAL->udev compat: yes Enable systemd login: no Enable TCP Wrappers: no Enable libsamplerate: yes Enable IPv6: yes Enable OpenSSL (for Airtunes): yes Enable fftw: yes Enable orc: yes Enable Adrian echo canceller: yes Enable speex (resampler, AEC): yes Enable WebRTC echo canceller: no Enable gcov coverage: no Enable unit tests: no Database tdb: no gdbm: no simple database: yes System User: pulse System Group: pulse Access Group: pulse-access Enable per-user EsounD socket: yes Force preopen: no Preopened modules: all Legacy Database Entry Support: yes
