Help us fix the bug :-)
As a workaround you can write a wrapper program that
1) opens alsa device (don't use legacy /dev/dsp)
2) only after that switches to voice-recording.state
3) streams data to stdout
and on reception of SIGINT first
4) switches back to streoout.state
5) closes alsa device
This can be done as a shell script that uses arecord.
