There has been some work and success with this in OwnTone: https://github.com/owntone/owntone-server/issues/1413
When comparing my two homepod mini's (set up as stereo pair) I have seen two service discovery outcomes for my actively playing stereo pair:
What they have in common:
gpn
(group name) is set on both devices (same as the name of the group leader)flags
has bit 13 set for the group leadergid
(group UUID) is the same for both devices - can be "single" UUID, or can be a "concatenated" UUID.Comparing the two situations in detail:
complete:
gpn
(group name) same on both (same as name for the group leader)flags
for group leader has bit 13 set: TightSyncIsGroupLeader
gid
(group UUID) same UUID on both devices (consist of tsid
UUID and a 2nd one)tsid
(?) set to same UUID on both devicesgcgl
(group contains group leader): set to 1 on both pgid
(parent group UUID) only set on the non-group-leader, has same value as gid
pgcgl
(parent group contains discoverable leader ) only set on non-group-leader, set to 1igcl
(is group leader) set to 1 for the group leader, 0 for the other deviceFormat for gid
/pgid
: <tsid-UUID>+0+<some-other-UUID>
incomplete:
Only gpn
and flags
are different between group leader and the non-group-leader. The flags are different than the complete example, but here as well: the group leader has bit 13 set.
gid
: same on both devices (format: single UUID, not the same as tsid
)tsid
: same on both devices (not used in gid
or pgid
) - and same as for complete example abovegcgl
: 0 on bothpgid
: same on both devices, same as gid
pgcgl
: 0 on bothigl
: 0 on bothDiffs for both situations:
After updating from 16.1 to 16.2 all values are still the same, except:
srcvers=670.6.2
osvers=16.2
any news / plans regarding support for homepod stereo pairs?
any news / plans regarding support for homepod stereo pairs?
No updates on that I'm afraid. It's a low priority for me right now, but certainly an interesting feature. At some point I might feel ready for it.
What feature would you like?
When streaming to a homepod stereo pair, I see both as individually addressable homepods, but not as a stereo pair. I'd like to be able to stream (and control) the stereo pair, rather than individuals.
Describe the solution you'd like
When scanning for devices, detect a pair and show as an additional device.
Any other information to share?
I'm attempting (unsuccesfully) to get around this via an apple TV paired to the homepods, but I imagine there are users without an apple tv that would want to do the same.
