Hello. :) 

I have experienced strange buzzing coming from my SB Audigy 2 ZS. 
Some very quick info:

 > uname -nv
 FreeBSD ... 8.1-RELEASE FreeBSD 8.1-RELEASE #0: ... amd64
 > cat /dev/sndstat
 FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
 Installed devices:
 pcm0: <EMU10Kx DSP front PCM interface> (play/rec) default
 pcm1: <EMU10Kx DSP rear PCM interface> (play)
 pcm2: <EMU10Kx DSP center PCM interface> (play)
 pcm3: <EMU10Kx DSP subwoofer PCM interface> (play)
 > pciconf -vlc 
 emu10kx0@pci0:4:1:0:	class=0x040100 card=0x00511102 chip=0x00041102 rev=0x03 
hdr=0x00
    vendor     = 'Creative Technology LTD.'
    device     = 'Audigy Audio Processor (Creative SB Audigy 2 ZS (WDM))'
    class      = multimedia
    subclass   = audio
    cap 01[dc] = powerspec 2  supports D0 D1 D2 D3  current D0

More details available on request. Googling around I found the following
link:

  http://lists.freebsd.org/pipermail/freebsd-multimedia/2010-October/011294.htm
l

which leads me to the way to fix this temporarily:

  # kldunload snd_emu10kx && kldload snd_emu10kx && mpg123 test.mp3
  (...repeat until it works...)

I'm wondering if a fix has been committed for this issue or a more
permanent workaround has been found? Thanks in advance.
