Maybe we could set the environment variable to the IPC key itself
then use something like:
pcm.dmix {
@args [ SLAVE FORMAT RATE ]
@args.SLAVE {
type string
default "hw:0,0"
}
@args.FORMAT {
type string
default S16_LE
}
@args.RATE {
type integer
default 48000
}
type dmix
ipc_key {
@func getenv
vars [ ALSA_DMIX_IPC_KEY ]
default { 12345678 }
}
ipc_key_add_uid no
slave {
pcm $SLAVE
format $FORMAT
rate $RATE
}
}
pcm.!default {
type plug
slave "pcm.dmix"
}
which is a slightly modified version of the default ALSA config file. Then
there'd be no need to generate config files or patch alsalib.
And yes, I know, possibly ALSA should not provide a mini API in its config
file but well that's an argument for upstream :) We have it, might as well
use it ...
