Everything seems normal but no sound is playing (windows to shairport, raspbian)

[gerar...@gmail.com]

Hi,

I'm trying to stream from a windows pc (sender) to a raspberry pi (receiver) which is connected through a DAC to a pair of speakers. Then, everything seems correct but there's no sound sounding. 

Some specifics about it:

1. - The rpi has correctly configured the sound, playing from rpi (mpg123, youtube) does play through the speakers without problem
   
   
2. - The rpi is recognized by tuneblade and can be connected to
   
   
3. - In the tuneblade window there is no "master" device, as it appears in the screenshot of the tuneblade main web page, I don't know if it should appear (?)
   
   
4. - When I play a mp3 file from the sender through vlc or just playing spotify there is no sound in the receiver, even though tuneblade is connected
   
   
5. - I've manually added the receiver device in tuneblade with a new name (the original auto-discovered one had a "_" character, which I've seen cannot be included in a custom name, so I though this might be a problem) but there's no difference
   
   
6. - I've tested all tuneblade streaming modes, no difference
   
   
7. - I've enabled/disables the tuneblade standby mode, no difference
   
   
8. - I've tried the direct loopback capture and the specific endpoint capture (towards the pc speakers, and towards other options), no difference
   *when in direct loopback, on some occasions the speakers are muted when playing, still no difference on the raspberry side
   
   
9. - the monitor tab in the tuneblade configuration shows nothing if the receiver is not connected, and it does show traffic when the receiver is connected. When the sender has something playing then the traffic amount significantly increases, so definitively something's happening (I guess, something is being captured and transmitted)
   

Then, what's wrong? The sender has windows 10 and receiver has the last raspbian version installed.

Thanks,

Ok, I've seen that it is actually streaming to the rpi only that sound output is the raspberry one, and not the DAC one.

However I solve this (any help is appreciated) I conclude then that it is nothing related to tuneblade, who is doing his job right.

Hi, 

Thank you for the detailed report. 

The master panel is optional, and can be enabled in the general settings of TuneBlade. This is useful only if there is more than one receiver, as with the master panel you can control volume and connection status of all of them with just one 'master' control. 

The manually added receiver need not have the name as the auto-discovered one. Currently, the manually added receiver cannot have special characters including the _, but we'll remove this limitation in the next version. 

Glad to know you figured out the cause of the issue to be configuration on the Pi, as it wasn't playing the stream on the DAC. Due to our limited knowledge on your RPi/ShairPort/Raspbian setup, we wouldn't be able to give you proper support on how to configure ShairPort to play audio to the DAC, we suggest you to check ShairPort or RPi forums as there are many users using similar setup, and we're sure you'll find a solution. This might be useful: http://drewlustro.com/hi-fi-audio-via-airplay-on-raspberry-pi/   . Check the sections "Make the Raspberry Pi prefer the USB sound card" and "Tell ALSA to use the USB hardware as it's default sound device"

If you need any further help from us, please do not hesitate. 

Thanks,
The TuneBlade Team

Thanks for the clarification. 

I finally have figure it out by using shairport-sync and marking as the output device "plughw:1,0". Credits for the people of iqaudio. Now it works perfectly :)
