M4A no sound

[bobred 0]

Hi

I am not getting any sound from some m4a Audible files, they play in windows but not on Emby using the web app in Firefox and Edge and no sound in Emby Theatre, but the Android app works. Attached are the logs.

Thanks

Hi, see above.

@FrostByte are you able to get sound with this file?

Would we not need a m4b file as that is what the transcode log shows?

"/volume1/Volume_1/Audiobooks/Celtic Mythology_ Tales of Gods, Goddesses, and Heroes/Celtic Mythology_ Tales of Gods, Goddesses, and Heroes--0007.m4b"

@bobred is this a m4a and m4b issue or just m4b?

I has no issues playing the provided m4a file in Firefox, Chrome or New Edge, it direct plays on my system.  I have a couple m4b files and do not see a issue with them transcoding in for Firefox either.  Unless this is a Synology specific issue but wouldn't think so.

Will have to search the forum but I thought we had a discussion on this as there are different types

my m4b

14:28:40.427     major_brand     : isom
14:28:40.427     minor_version   : 512
14:28:40.427     compatible_brands: isomiso2mp41

from OP log

13:33:40.966   Metadata:
13:33:40.966     major_brand     : M4A 
13:33:40.966     minor_version   : 512
13:33:40.966     compatible_brands: isomiso2

Will update when/if I find that discussion.

@Luke Is this still a future enhancement as your last comment would suggest at the end of this topic discussion?  Also referenced Synology/Firefox.  

 

Looks like that may only be in reference to Chapters after re-reading.

Well audio book features are yes, but in terms of just playing the file, it should be able to play now.

This appears to be both.

Hi

It is working now. I tried playing something that I know to play and no sound! Turns out the sound card was set to 5.1 output instead of direct, not by me????

I don't know what was wrong initially as I had sound from Windows Media player for m4a/b and but not Emby, mp3 played on everything.

Thank you all for looking into this though.

Thanks for the feedback.
