Learnings about Group - Memory

[maximoei]

Done some further digging into the different group functions. Since latest PRs, now have confirmed that following are working in my set up (XT-2 + X-88 + X-77)

• Create / Start group
• Abort group
• Mute group
• Change group volume

Not working

• Stop
• Play

Furthermore; the GetAllGroupMemory works, and returns the last five groups in XML embedded Json:
Memory: {'GroupMemory': '<?xml version="1.0"?>\n<groupMemoryList>\n <groupMemory>\n <MemoryID>7</MemoryID>\n <GroupMode>GROUP</GroupMode>\n <GroupName>Test</GroupName>\n <SlaveList>uuid:00000000-0000-1010-8000-ac9b0a2163d9,uuid:00000000-0000-1010-8000-ac9b0a300c02</SlaveList>\n <CodecType>64</CodecType>\n <CodecBitrate>3</CodecBitrate>\n </groupMemory>\n <groupMemory>\n <MemoryID>6</MemoryID>\n <GroupMode>GROUP</GroupMode>\n <GroupName>Link</GroupName>\n <SlaveList>uuid:00000000-0000-1010-8000-ac9b0a2163d9</SlaveList>\n <CodecType>64</CodecType>\n <CodecBitrate>3</CodecBitrate>\n </groupMemory>\n <groupMemory>\n <MemoryID>5</MemoryID>\n <GroupMode>GROUP</GroupMode>\n <GroupName>Gekoppeld</GroupName>\n <SlaveList>uuid:00000000-0000-1010-8000-ac9b0a2163d9</SlaveList>\n <CodecType>64</CodecType>\n <CodecBitrate>3</CodecBitrate>\n </groupMemory>\n <groupMemory>\n <MemoryID>4</MemoryID>\n <GroupMode>GROUP</GroupMode>\n <GroupName>Group</GroupName>\n <SlaveList>uuid:00000000-0000-1010-8000-ac9b0a2163d9,uuid:00000000-0000-1010-8000-ac9b0a300c02</SlaveList>\n <CodecType>64</CodecType>\n <CodecBitrate>3</CodecBitrate>\n </groupMemory>\n <groupMemory>\n <MemoryID>3</MemoryID>\n <GroupMode>GROUP</GroupMode>\n <GroupName>Group</GroupName>\n <SlaveList>uuid:00000000-0000-1010-8000-ac9b0a2163d9</SlaveList>\n <CodecType>64</CodecType>\n <CodecBitrate>3</CodecBitrate>\n </groupMemory>\n</groupMemoryList>\n'}
Don't know how to apply the other Memory related functions; would expect a StartM based on group id to recreate a group, but that doesn't exist.

Anyway, latest changes are already useful. @rytilahti , can a new release be created? I'm working on building support into HomeAssistant to create/abort groups.

Okay, let's keep this issue open in case something new comes up, it could be that those commands take the parameter in somehow, but the service description file just doesn't list all the parameters. One way to find out would be to see if the mobile app provides this functionality and do a packet capture to see what is happening.

I'll prepare a new release this week, btw, you are likely interested in home-assistant/architecture#364 for homeassistant. Also related #49.

Is it able to create a group with the device not supporting wireless surround? like st5000.
If not, is it able to add this to support list by myself using the audio api? Willing to make group with st5000 and 2 zr5.
thx

@osk666neo666 check the output of songpal discover, if the relevant devices are listing urn:schemas-sony-com:service:Group:1 in the supported services, it may be doable.
