Volume control via bypassSinkVolume

First of all I would like to thank you for the great project, as Spotify does not want to implement an integration for the Apple HomePod.

With spocon, I send the “music” to owntone via PIPE. From there I can wonderfully send the music to the HomePods via Airplay. With the latest changes there are almost no more delays in play and stop! 😃

My configuration

[player]
	# Whether to apply the Spotify loudness normalisation
	enableNormalisation = true
	# Initial volume (0-65536)
	initialVolume = 5243
	# Whether librespot-java should ignore volume events, sink volume is set to the max
    bypassSinkVolume = true
	# Release mixer line after set delay (in seconds)
	releaseLineDelay = 20
	# Normalisation pregain in decibels (loud at +6, normal at +3, quiet at -5)
	normalisationPregain = 3.0
	# Output metadata in Shairport Sync format (https://github.com/mikebrady/shairport-sync-metadata-reader)
	metadataPipe = "/srv/music/spotify.metadata"
	# Autoplay similar songs when your music ends
	autoplayEnabled = true
	# Preferred audio quality (NORMAL, HIGH, VERY_HIGH)
	preferredAudioQuality = "VERY_HIGH"
	# Where librespot-java should search for local files
	localFilesPath = ""
	# Audio output device (MIXER, PIPE, STDOUT, CUSTOM)
	output = "PIPE"
	# Crossfade overlap time (in milliseconds)
	crossfadeDuration = 0
	# Whether the player should retry fetching a chuck if it fails
	retryOnChunkError = true
	# Audio output Java class name
	outputClass = ""
	# Mixer/backend search keywords (semicolon separated)
	mixerSearchKeywords = ""
	# Output raw (signed) PCM to this file (`player.output` must be PIPE)
	pipe = "/srv/music/spotify"
	# Log available mixers
	logAvailableMixers = true
	# Number of volume notches
	volumeSteps = 64

With the configuration: bypassSinkVolume = false I can change the volume, but it is very offset in time.

With bypassSinkVolume = true I can change the volume in Spotify, but this has no effect.

What am I doing wrong? Or is that a bug?

I’m not familiar with this but does indicate that owntone is receiving the volume commands. You might need to speak with the owntone dev to enquire what this means.

Do you use purely airplay devices with owntone?
