A common cause of this type of bug is that some other program (e.g. linphone or speech-dispatcher) starts concurrently with PulseAudio and also probes all ALSA devices. Therefore, PulseAudio sees the device as being busy and thus unavailable, and never retries. The correct fix would be to reconfigure that other program to use PulseAudio. -- Alexander E. Patrakov
