Probably it was working deterministically only by luck before :/

You can specify the device to be used in
/etc/speech-dispatcher/speechd.conf, the AudioALSADevice parameter. You
can check the available device names in /proc/asound/cards, e.g. on my
system:

 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0x91338000 irq 139

means I can specify PCH as device name.
