For those of you using ALSA and jack there may be immediate relief.
The ALSA jack plug slave PCM device and the aoss dspN devices
appear to work together without incident. So, if you put the
following in $HOME/.asoundrc:
pcm.jackplug {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}
pcm.dsp0 {
type plug
slave.pcm "jack"
}
you can run any ALSA-based program with jack using 'jackplug' as
the device. You can run an OSS-based program under jack via oss.
For example, the digital mode program gmfsk can be run with
aoss gmfsk
This doesn't solve all jack ills, but it does satisfy a number of
important cases without drastic rewriting or kludging.
