ogg & moode

[Phil35]

Hi,
I'm apologize for this certainly basic question for moode expert.

When I select mp3 file, everything is fine,  ie music is well sent using bluetooth to my sound system which uses WTX-700
when I select ogg file, the message displayed is:
"Failed to open "ALSA Bluetooth" (alsa); Error opening ALSA device "_audioout"; snd_pcm_hw_params() failed: Invalid argument"

What is wrong?

What audio format is there in the OGG container:

On my moOde 8.0.2, the OGG/OGA supported ones are VORBIS, FLAC and OPUS (as you can check running mpv --version on your RPi)
I believe any codec other than these is not supported.

[vorbis] ogg oga
[oggflac] ogg oga
[opus] opus ogg oga

Hi,
Thank you for your answer.

ogg is there, but it doesn't work.

When I read "What audio format is there in the OGG container:"
The ogg files were created using audacity software (latest version 3.2 audacity-linux-3.2.0-x64.AppImage) with default parameters.
How to inspect ogg files?

Thank you
Phil

I found this: oggz-tools under linux. Vorbis seems here. isn't it ?

$ oggz-info "Many rivers to cross - face A.ogg"
Content-Duration: 00:03:04.214

Vorbis: serialno 1630527556
17223 packets in 891 pages, 19.3 packets/page, 1.252% Ogg overhead
Audio-Samplerate: 44100 Hz
Audio-Channels: 2

Zip up one of the ogg files and PM a download link to myself and @TheOldPresbyope. One of us will analyze it and see what might be happening.

The OGG file plays fine MPD -> audio device.

Are you playing MPD -> Bluetooth -< Bluetooth speaker?

@Phil35

Hi, Phil.

Got your file. Off the top of my head, it looks good and it plays fine in moOde 8.2.0 using my Creative Tech USB-W2 audio adapter (which transmits aptX Bluetooth to my Sennheiser headphones; it is seen by Linux as a audio device, not a Bluetooth device). All default audio settings. Here's the audio info provided by moOde during playback

Code:

INPUT / OUTPUT
Source              SDCARD/Many rivers to cross - face A.ogg
Encoded at          f bit, 44.1 kHz, Stereo Vorbis
Decoded to          24 bit, 44.1 kHz, Stereo,
Output rate         16 bit, 48 kHz, Stereo, 1.536 Mbps
Output mode         ALSA Default (plughw)
Output chain        MPD -> plughw -> Device
Loopback            off

The command line tool mediainfo tells much the same story.

...BUT...

when I enable the moOde Bluetooth renderer, connect to a JBL Bluetooth speaker, and switch MPD audio output to Bluetooth, I get the same error as you do. 

Ah, before enabling the Bluetooth renderer try going to MPD settings and enable SoX Resampling with 16 bit depth. That did do the trick for me...just don't ask me why it works.  (I believe it has to do with that "f bit" encoding. I promise I'll figure it out...eventually.)

Fascinating track, by the way. I've never heard it before but I love it.

Regards,
Kent

I had the same result but forgot about the SoX workaround. AFAIK this issue came up in the early days for OGG format.

The conf is specifying plughw which should auto convert to 16 bit but for some reason it's not liking OGG.

Code:

pi@moode:~ $ cat /etc/bluealsaaplay.conf
# bluealsaaplay.conf
AUDIODEV=plughw:0,0
BUFFERTIME=500000

Maybe just convert the OGG's to some other format that works with Bluetooth -> speaker.

Hi @Tim Curtis  & Hi @TheOldPresbyope ,

First thank you for your time, I really appreciate.
and for the tips found, I will test on monday, I cannot test before / sorry.

The overall configuration is:
[ Raspberry Pi 3 Model B Rev 1.2 ] -> [ bluetooth of the raspberry ] --> [ WTX-700 (see https://www.cobra.fr/advance-wtx700-p-47299)  ] [ connected to hi-fi system ]

What do you think about, what is your suggestion about:  
buy an USB bluethooth device like "Creative Tech USB-W2" or still use the bluetooth from the raspberry ?
(for example I found W3 and W4 : https://us.creative.com/wfh/#fix-your-audio,  W2 is no more available now)

Yes the song is great ... 1969 however but still so good.
I am recording old old vinyl disks  45t and 33t :-) .  I guest ogg was better than mp3, but may be I wrong.

Kind regards
Phil

Just a tip, but when you digitalize old music media like records etc, best is then to rip to flac. In that way you preserve highest audio quality. If needed you can then always make MP3, ogg, whatever needed out of it later.
