>Regarding "latency", when default-fragment-size-msec was 10000, I
noticed a line saying
>( 124.922| 0.000) D: [alsa-sink] sink.c: latency = 1339
the buffer size of hda in ubuntu 12.04 seem reduced from 4mb back to
64kb
configured latency: 20.00 ms; range is 1.00 .. 371.52 ms
card: 0 <alsa_card.pci-0000_00_14.2>
module: 4
properties:
alsa.resolution_bits = "16"
device.api = "alsa"
device.class = "sound"
alsa.class = "generic"
alsa.subclass = "generic-mix"
alsa.name = "ALC889 Analog"
alsa.id = "ALC889 Analog"
alsa.subdevice = "0"
alsa.subdevice_name = "subdevice #0"
alsa.device = "0"
alsa.card = "0"
alsa.card_name = "HDA ATI SB"
alsa.long_card_name = "HDA ATI SB at 0xfe024000 irq 16"
alsa.driver_name = "snd_hda_intel"
device.bus_path = "pci-0000:00:14.2"
sysfs.path = "/devices/pci0000:00/0000:00:14.2/sound/card0"
device.bus = "pci"
device.vendor.id = "1002"
device.vendor.name = "Advanced Micro Devices [AMD] nee ATI"
device.product.name = "SBx00 Azalia (Intel HDA)"
device.form_factor = "internal"
device.string = "front:0"
device.buffering.buffer_size = "65536"
device.buffering.fragment_size = "32768"
does it mean that pulseaudio server it own buffer 1000ms when the driver
only has 371.52 ms ?
