MP3 audio not playing to COAX
#1
Hi,
I am having trouble with XBMC Live Dharma beta 3.

For some reason I am not able to play audio of files containing MP3 @ 44.1kHz.
All the other formats (DD, DTS, etc.) work fine.

The relevant part of the debug log into the xbmc.log is:
Code:
DEBUG: FactoryCodec - Audio: PassthroughFFmpeg - Opening
11:58:03 T:2883840880 M:875573248    INFO: CDVDAudioCodecPassthrough::Open - disabled passthrough due to sample rate not being 48000
11:58:03 T:2883840880 M:875573248   DEBUG: FactoryCodec - Audio: PassthroughFFmpeg - Failed

The full log (since the start of the movie) is:

My config:
XBMC Dharma beta 3
Intel E4300 - 1GB RAM
Audio: C-Media 8768 (Manhattan PCI Sound card)
Video: nVidia 8600GT

Is there any way to enable the MP3 files on the COAX output?

See this topic (reply No. 10) for more details. From your first post: "CDVDAudioCodecPassthrough::Open - disabled passthrough due to sample rate not being 48000". It appears that Xbmc will (for the moment) NOT pass through 44.1 kHz streams. Which is silly. Try the following fix/workaround.

  1. Createl a file called: /home/my_name/.xbmc/advancedsettings.xml
  2. Paste the following text in it:
    Code:
    <advancedsettings>
            <audio>
                    <dvdplayerignoredtsinwav>true</dvdplayerignoredtsinwav>
            </audio>
    </advancedsettings>
Good luck! Smile

Tried that, but did not work.

Anyone could help me?

Whenever I start a movie with MP3 audio or a music (flac, ape, mp3) the sound is muted and the passthrough is disabled.

How can I force passthrough even if the sample rate is not 48000?

please help.
Quite a blocking situation.

You are using the Live CD aren't you? I haven't succeeded either in getting pass tru w/ Live. I'll try to keep keep an eye on to your topic see if there will be a solution. You can keep an eye on this topic and this topic to see if I found one Wink

P.S. It might be better for clarity to keep all passtru w/ Live probs. in one topic... Even though some devs deny there's a prob: believe me: there is!

Hi,
thanks for your support!

I have apparently managed to solve partially the problem: in alsamixer the SPDIF OUT was 'OFF'.
Strange because the .mkv video were working fine. Only MP3 movies and music, flac and skin sounds weren't working.

Now I have MP3 and flac working.

The only thing that are not working are the skin sounds, but I can live with it.


Will keep an eye in those threads though just to see if someone comes out with a solution to the skin sounds.

thanks again.

So you installed Xbmc Live to harddisk, did you? Because that way you can access alsamixer. I think that's the reason why, when I run xbmc from live CD, I cannot get dig. out! Laugh

Yes. I have Live installed onto the HD.
That's my conf.

I will test more deeply to see if all the formats are played fine.
