I have not tested it since the module was made standalone. No one has 
reported using it with your plantronics m2500 headset. Do you have a 
different adapter (like a CSR-based usb) you could try it with by the way?

does it exit immediately or after a timeout?

if you're using gnome, be sure to "esdctl off" so you're not competing 
with esound.

i had to get everything just perfect with alsa before it would work. 
what does the also stuff in modules.conf look like? mine is:

options snd major=116 cards_limit=2 device_mode=0660 device_gid=29 
device_uid=0

alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

alias snd-card-0 snd_intel8x0
alias snd-card-1 snd_bt_sco
#alias snd-card-2 snd-share
#alias snd-card-3 snd-virmidi

alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-1
alias sound-slot-2 snd-card-2
alias sound-slot-3 snd-card-3

also i found my "alsasound" script under debian was not set up to start 
at boot.

give us line numbers or a patch please.
