for unknown reason which pulseaudio did not probe surround40
pulseaudio still using timer base scheduling in your last log but it was strange tradtional mode was used in your first log 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.name = "CA0106" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.id = "ca0106" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.subdevice = "0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.subdevice_name = "subdevice #0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.device = "0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.card = "0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.card_name = "CA0106" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.long_card_name = "Live! 7.1 24bit [SB0410] at 0xcf00 irq 19" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: alsa.driver_name = "snd_ca0106" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.bus_path = "pci-0000:06:00.0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: sysfs.path = "/devices/pci0000:00/0000:00:1c.3/0000:05:00.0/0000:06:00.0/sound/card0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.bus = "pci" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.vendor.id = "1102" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.vendor.name = "Creative Labs" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.product.id = "0007" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.product.name = "CA0106 Soundblaster (SB0410 SBLive! 24-bit)" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.string = "front:0" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.buffering.buffer_size = "65536" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.buffering.fragment_size = "32768" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.access_mode = "mmap+timer" Jan 02 20:25:49 homecomp pulseaudio[11971]: [pulseaudio] sink.c: device.profile.name = "analog-stereo" Dec 25 19:33:27 homecomp pulseaudio[1911]: module-stream-restore.id = "sink-input-by-application-name:paplay" Dec 25 19:33:27 homecomp pulseaudio[1911]: Requested tlength=2000.00 ms, minreq=20.00 ms Dec 25 19:33:27 homecomp pulseaudio[1911]: Traditional mode enabled, modifying sink usec only for compat with minreq.
