Hmm, well, Teamspeak uses it, too.. And i can imagine that there's a
whole bunch of others.. I wonder, if using libc's fopen() for accessing
/dev/dsp is "wrong". And i also wonder if this is documented
smoewhere... Oh, and the aoss-docs also don't talk about mmap'ed sound
access. Games like Enemy Territory and Quake3 use OSS and mmap'ing. I
didn't get ET to use sound with aoss [I always get an error like:
"/dev/dsp: Invalid argument Could not mmap /dev/dsp"].. What is the
status of mmap emu with aoss?
Here's my .asoundrc. I experimented with turning on mmap emulation for
my hw:0,0 alias to no avail:
pcm.hardware {
type hw
card 0
device 0
mmap_emulation true
}
#asym fun start here. we define one pcm device called "dmixed"
pcm.dmixed {
ipc_key 1025
type dmix
slave {
pcm "hardware"
# pcm "hw:0,0"
# period_size 2048
}
}
#one called "dsnooped" for capturing
pcm.dsnooped {
ipc_key 2027
type dsnoop
# slave.pcm "hw:0,0"
slave.pcm "hardware"
}
#and this is the real magic
pcm.asymed {
type asym
playback.pcm "dmixed"
capture.pcm "dsnooped"
}
#a quick plug plugin for above device to do the converting magic. saves
#typing when settng the pcm name in an alsa app
pcm.pasymed {
type plug
slave.pcm "asymed"
}
#a ctl device to keep xmms happy
ctl.pasymed {
type hw
card 0
}
#the default pcm device for alsa apps:
#pcm.!default {
# type plug
# slave.pcm "asymed"
#}
#here we try to point the aoss script to our asymed device
pcm.dsp0 {
type plug
slave.pcm "asymed"
}
ctl.mixer0 {
type hw
card 0
}
#done
