Yes, i've tried that a while ago. From a former posting:

| I've made a small diff (for Version 1.0.1)
|
| http://217.115.144.27/~praml/vdr-1.0.1-mp3-soundcard.diff
|
| The PCM data is sent through a pipe to 'aplay' (or any other
| player that accepts s16_be (stereo 16 bit big-endian) PCM data)
|
| Before and after MP3 playing, I execute a command to set/mute the SPDIF
| of the soundcard. (my hardware setup:
| DVB-SPDIF ----> CM8738 ----> SPDIF in of Amplifier
| So, I only need one SPDIF connection to the amp.)
|
| The main advantage is that the sound is more clearly (no clicks on
| OSD activity) and the card isn't blocked for recording (i didn't try that
| yet)
|
| Disadvantage:
| the latency is increased a little bit because of the buffer in aplay. (~
0.5
| sec)
