[mythtv-users] Playing a sound during Live TV/Recordings

[Eni Gma]

I am having a little problem with Myth upon which I was hoping somebody 
could shed a little light.  I use a remote control to control my 
frontend boxes.  I would like a small sound to play each time I press a 
remote key so I can tell if the computer received the key or if Myth is 
hung or waiting.  Just a little user feedback to aid navigation.  I set 
up irexec to play a click when any key is pressed, and it works 
fantastically in menus and the EPG.  However, when I am watching Live TV 
or a recording once the application takes control of the DSP I can no 
longer play my little sound.  The sounds queue up and when I return to 
the menus I get a torrent of clicks, one for each keypress while I was 
watching the video.  The clicks work under MythVideo (mplayer) but do 
not work under MythTV.

Is there any way I can play a sound when Myth has control of the DSP? 
 Is there a non-blocking DSP device available, or does Myth perhaps make 
a facility available to play audio?  Any info on this subject is 
appreciated.
