Re: Occasional metallic sound when recording (cs46xx)

[Joe <madcoder@comcast.net>]

I have the same problem with my Turtle Beach Santa Cruz card (cs46xx). 
I haven't used the capture device yet, but the metallic sound happens in
playback, also randomly.  For example, in gaim, incoming IM sounds will
be normal, and then all of a sudden, switch to that metallic sound (the
source sound file is the same, but the playback is extremely
different).  It seems to be a problem that is triggered only when
opening the device, because it happens in XMMS as well, when playing a
song file -- if this anomaly is triggered when the song is started, it
remains throughout he entire song, unless stopped and restarted, or
going to the next track.  

I hope this helps someone understand the problem, but I'm afraid I can't
tell what is the actual trigger for it.
