Hi Andy, I'm traveling on business for about two weeks, so I won't be able to look into this right now. Any idea whether this is some new regression? I'm just trying to understand whether this is something that has always been there since I originally added the ALSA support to cx18 or whether it's something that is new, in which case it might make sense to drag the ALSA people into the conversation since there haven't been any changes in the cx18 driver lately.
