Having played a bit with the new sound system in 0.24, I have to say, I<br>
like it's direction. I find that there could be more options though.<br>
<br>
Recently I reported a bug about AC3 stereo not being passed through to<br>
the receiver. I reported it because I thought it was a bug, but that's<br>
not to say I didn't like the behaviour. I do prefer to have AC3 decoded<br>
by Myth because my receiver has some latency (and a click) between when<br>
it starts getting an AC3 track and when it starts decoding/playing it.<br></blockquote><div><br>if you want AC3 to be decoded by myth, uncheck AC3 passthrough.<br>I understand what you are saying, and read below<br><br></div>

<br>
So it seems that what I would want to do is disable DD and DTS in my<br>
Myth config and enable LPCM, which I am guessing indicates to myth that<br>
I want it to do the AC3 decoding. That's fine, except that the<br>
connection between my TV and my receiver is optical (and my FE->TV is<br>
HDMI) and so not capable of carrying 5.1 on LPCM (as far as I<br>
understand), but only 2.0.<br>
<br>
So what I would like to tell Myth is, that if the sound is AC3 and it's<br>
2ch (or less), decode it and send it over LPCM, but if it's more than<br>
2ch and it's DD or DTS then pass it through to the receiver for<br>
decoding.<br></blockquote><div><br>I won't be adding such option. The idea is to simplify the setup, not make it once again overcrowded with options 99% of the people won't use<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<br>
In order to achieve that it seems that I need an option box to tell Myth<br>
to prefer decoding AC3 itself when possible and I also need an input box<br>
to tell Myth how many channels it can use LPCM to send to the reciever.<br></blockquote><div><br>This is already done internally.<br>Myth knows how many pcm channels the audio card support.<br><br>so if using spdif, it will send PCM for stereo only, anything multichannels will be sent as DTS or AC3.<br>
<br>For hdmi, multichannels audio will be sent as LPCM where it can, or DTS/AC3 if passthrough has been selected.<br> <br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
<br>
With regard to this latter option though, perhaps many people don't<br>
understand the abilities of HDMI vs. toslink so perhaps rather than a<br>
more technical option like specifying how many channels can be carried<br>
to the receiver a more simple/consumer-like option to specify whether<br>
your receiver is connected via optical cable or HDMI should be provided<br>
and from that, Myth determines how many channels it can send with LPCM.<br>
<br></blockquote><div>it already does that<br><br></div></div>
