An with "hw", you have disabled any automatic format conversion. Try "plughw:2" or "default:2".

Could you be kind enough to suggest how I should write .asoundrc?

I only know the obvious one for jack:

.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 } } ----------------
