Repeating error of squeezebox media player component in 0.115

[Spirituss]

The problem

After update to 0.115 the HA log gets repeating error every 4-5 sec.

Environment

• Home Assistant Core release with the issue: 0.115.3
• Last working Home Assistant Core release (if known): 0.114
• Operating environment (OS/Container/Supervised/Core): Docker/Core
• Integration causing this issue: Squeezebox (?)
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/squeezebox/

Problem-relevant configuration.yaml

No yaml, since squezeebox integration works now via GUI setup.

Additional information

Media players more or less stay working even with this errors.

[gijbelsy]

I can confirm this.
I'm having the same issue too, since update to 0.115.
Removed the integration, reinstalled ... issue remains.

I think this has something to do with the feedback of squeezebox, since the issued command is beeing execuded on LMS itself.
An example:

- service: squeezebox.call_method data_template: entity_id: "{{ player }}" command: power

Selected player toggles it's power, but every time the message as described by @Spirituss appears in the log.

[Spirituss]

UPD: this issue significantly affects HA performance - my HA becomes almost unworkable with squeezebox media players. I totally removed this integration and CPU load decreased about 10-20%. Thus, please, find a fix as soon as possible.

[ResteNarquois]

It seems to be choking on reporting the media_content_id as part of the player attributes.

Furthermore, if the media_content_type is playlist and the playlist is empty, it throws the error. I can toggle players with empty playlists, but HA throws the error in the frontend, and doesn't update the power state.

Trying to see if keeping at least some type of playlist on each player will reduce the frequency of the errors in the logs.

I've had similar issues with the ADS component after update to 0.113:
#38150
In the end it had something to do with async not handling the received packets correctly.

[FuzzyMistborn]

Are you guys on 8.0 of LMS or 7.9.x?

[gijbelsy]

7.9.3, the latest available version for piCore.

Logitech Media Server version: 7.9.3 - 1597753178 @ Sun Aug 23 19:27:27 CEST 2020
OS: piCore - NL - utf8
Architecture: armv8l-linux
Perl-version: 5.28.2 - arm-linux-gnueabihf-thread-multi-64int
Audio::Scan: 1.02
IO::Socket::SSL: 2.066
DB Version: DBD::SQLite 1.58 (sqlite 3.22.0)

[FuzzyMistborn]

Ok so it's not LMS version dependent as someone on Discord was running 8.0 and I'm on 7.9.4 and still getting the error.

[gijbelsy]

Manually forced upgrade to 8.0.0 - 1601380107 @ Tue Sep 29 14:25:05 CEST 2020:
Problem remains.

[Paul-Faulkner]

This appears to happen when the playlist in the Logitech Media Server is cleared. If you add any song then the error disappears. For now I'm just pausing the playlist rather then clearing it - seems to prevent the error in HA.

[Spirituss]

@Paul-Faulkner
I added songs to all of my players but it doesn't work.

[gijbelsy]

@Spirituss: I can confirm that the workaround as proposed by Paul-Faulkner works in my case.

[Spirituss]

Are the integration developers still here? The error log is quite noisy now

[Spirituss]

Guys, any news on the possible fix?

I've noticed y'all have made some commits lately. Can you have a look concerning this issue, or give us an update?
