B&W Zeppelin AIr as USB DAC

tmilovan

Hello,

I'm trying to use B&W Zeppelin Air over USB as DAC and speaker and all works fine except I cannot use software volume control nor can I control the volume with external Zeppelin's volume control. The only way I can affect volume is via alsamixer and even there only PCM control is available.

Is there anything I can configure so I get a little more control over Zeppelin Air unit?

Thanks.

Hi tmilovan,

your B&W Zeppelin Air is not selected as output device.

Please go to MENU->MPD and select it as your "Audio output interface".

Next thing is that you have enabled the "iqaudio-dac" in /boot/config.txt, but this hardware is not available.
I also can see from your log that you are not using wifi, so please do this:

systemctl disable netctl-auto@wlan0

you will get much shorter boot time.

If you like you can also try the latest version of RuneAudio for RP2/RP3 (see download page).

Ah sorry it must have switched card back to default while I was turning Zeppelin off and on again. Here is the correct debug output: http://pastebin.com/SRbVHXyk

Also, I have found out that volume does not work only when streaming Spotify. With everything else it works fine.

And thanks for the rest of the tips:) I'll try the new image as soon as I manage some time to write it to sd card.

Thank you.

Hi tmilovan ,

Also, I have found out that volume does not work only when streaming Spotify. With everything else it works fine.

this is normal behavior (see here).

To get hardware volume to work we have to first add your B&W DAC to our database.
