[vdr] Re: no more sound when switching channel from AC3 to PCM

["karim" <karim.afifi@free.fr>]

Hi Klaus,

I am not enough "technical" to understand why my amplifier
=> stays mute after a first switch from AC3 to PCM channel.
=> return sound after a second swith from PCM to PCM channel.

But it seems that the amplifier must receive "two inits" to accept remaining
from AC3 mode to PCM mode.
Then, do you think that a workaround like below could be possible ?
*only* if a switch from AC3 channel to PCM channel is detected, then
vdr will simulate two switches to PCM, to be sure that the amplifier won't
hang.

Sorry if I am wrong ;-)  it's only an idea ...


Bye !
Karim.

I wouln't know what to do about this in VDR itself...
