No sound with shairport on Raspberry Pi 4

[mbundes]

When shairport is started on Pi, sound redirected from my MacBook Pro or Iphone to the shairport server running on Pi, I cannot hear sound. Spotify on Home Assistant server work correctly.

Thanks for the post. In the log above, it looks like Shairport Sync is already running as a daemon -- it's using port 5000.

Shairport Sync is set to output to the default device. If you haven't changed the alsa defaults, that may be the headphone jack or the HDMI output. (I never change the alsa settings and In my experience, the default is always the headphone jack.) However, as set up, Shairport Sync does not control the hardware mixer (i.e. the hardware volume control), so it is possible that all you need to do is turn up the mixer level on the default output card. You can use alsamixer for that. When you get it going, you can hook the mixer control up to Shairport Sync.

[mbundes]

Thanks for your answer. 5000 port use for Home Assistant. Yes, I need jack connection. Can we change port here? Can you give me simple instructions? 😊 Thanks

[mikebrady]

You can change port in the configuration file, sure.

[mbundes]

Only change port in config? 😳

[mikebrady]

Also on the command line.

[mbundes]

Changed the port three times. The service was restarted. The error is the same.

Is Shairport Sync also running as a daemon? (See above.)

[mbundes]

$ sudo service shairport-sync restart done

How else to check?

[mikebrady]

Thanks. I'm afraid you'll have to educate yourself about standard Linux techniques -- that's not really our role.
