Package: audacious
Version: 2.1-1
Severity: normal

  Found on Audacious 2.1-1, kernel 2.6.30-1-amd64 (2.6.30-5), hda-intel with
NVidia MCP61.
  Using top, the process hd-audio0 (kernel internal) consumes 46% of 1 CPU
while Audacious plays, doesn't happen with other programs AFAICT.
  The audacious2 process only consumes 2%.
  In my dmesg I see one
"hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj."
and some "Too big adjustment 32", which I don't know if they are related.
  The "Too big adjustment 32" happens once per every song I play in Audacious
and not for other programs.
  Maybe this is a kernel issue, though it didn't happen with Audacious 1.5.1
and doesn't happen with other audio applications.
  The hw_params and sw_params with Audacious:
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 32
buffer_size: 1024

tstamp_mode: NONE
period_step: 1
avail_min: 32
start_threshold: 1
stop_threshold: 1024
silence_threshold: 0
silence_size: 0
boundary: 4611686018427387904

  The hw_params and sw_params with MPlayer:
access: RW_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 44100 (44100/1)
period_size: 1024
buffer_size: 16384

tstamp_mode: NONE
period_step: 1
avail_min: 1024
start_threshold: 1024
stop_threshold: 4611686018427387904
silence_threshold: 0
silence_size: 4611686018427387904
boundary: 4611686018427387904

  In Audacious I am using the ALSA-NG output plugin with "hw:0,0" as audio
device, 16 bit output depth, output rate converter disabled, and
"bypass all of signal processing if possible" enabled.
  The problem goes away if I select the "default" audio device, but then the
sound card runs with 32 bits of depth and 48000hz, even if the songs are
44100hz.
  I don't want to use a rate conversion from 44100 to 48000 if the card
is able to internally operate at 44100, it seems to be a waste of CPU and
sound quality to do that.

  Some PCI info:
00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)
        Subsystem: ASRock Incorporation Device 3662
        Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 22
        Memory at df7f8000 (32-bit, non-prefetchable) [size=16K]
        Capabilities: [44] Power Management version 2
        Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+
        Capabilities: [6c] HyperTransport: MSI Mapping Enable- Fixed+
        Kernel driver in use: HDA Intel

  Any suggestions?
  Thanks!!!
