If "audio device" == ALSA card, yes you can if the card has more than one
ALSA device (e.g. line-in and mic).

If you mean one ALSA card with one ALSA device, you can only if the hardware
and the driver do provide this capability, but the two apps must use
different subdevices and thus different sources. Two apps cannot open the
same card:device:subdevice at the same time.
