 > This ticket has been open for a while, I hope people are still looking
 at it. I also have a DViCO Fusion 5 Gold card and am having problems with
 the sound and channel change. I've described my experience here
 http://www.mythtv.org/wiki/index.php/DVICO_FusionHDTV5_Gold . My problems
 are essentially the opposite of what the ones this guy was having. I have
 sound until I try to change the channel.

 This is a driver bug, I believe.  Note this change: [http://linuxtv.org/hg
 /v4l-dvb?cmd=changeset;node=fcbc40540e1b;style=gitweb]  Also note that if
 you build the latest linuxtv snapshot it doesn't fix it, because the
 define in this change set (CONFIG_VIDEO_CX88_ALSA) doesn't get defined
 (CONFIG_VIDEO_CX88_ALSA_MODULE does, though).  Easiest thing to do is to
 just comment out the stop/start DMA lines.

 However, this doesn't impact the original bug of no sound on initial
 tuning.  I'm getting a similar issue; it's not that there's no sound, but
 that the sound is set to the wrong sample rate.  My card only supports
 48000, anything else and you get garbage.  I am not sure this is the same
 problem as changing channels _doesn't_ fix it.  Leaving LiveTV and coming
 back does.
