If you change your default sound card to the Audigy one, there should be a 'defaults.pcm.card' setting in ~/.asoundrc (if you use Breezy) or ~/.asoundrc.asoundconf (if you use Dapper). Can you please edit that file and manually add a setting 'defaults.pcm.ctl' with the same value as 'defaults.pcm.card' has? Does it work correctly then? If so, this is just another consequence of bug 35540.
