Muse Luxe esphome loud buzzing sound

Hey, I’m flashing this firmware:

And it works in home assistant, except there is this loud buzzing noise, it’s so loud it’s unbearable.
This noise only starts when the device boots up. On the squeezelite firmware there is no buzzing sound.

Anyone else having this issue?

Now that I have gotten squeezelite to play audio from home assistant, it too starts playing this buzzing noise as soon as anything plays on the speaker, until I restart it

Hi LatherConch,

I have never had a report of such a thing, or maybe only whe the battery is almost empty.
I recommend that you ask for a replacement thru Amazon, it’s quick and free.

Sorry for the trouble, I will check your unit whe it will be sent back to me.

After reflashing a couple of times, this seems to have fixed itself, I’m unsure how to reproduce it again. Especially cautious now since I’ve finally gotten squeezelite to work with HASS.

I’ve the same issue. There is sometimes (once or two times a Day) this loud static sound for only a second. it startled us so much every time that i had to switch it of until I’ve found the issue.

Hard to diagnose :sweat_smile: is it on battery only or even when plugged?
I there something in the Squeezelite logs when this is happening?

I have noticed that when the battery is almost empty you could have some strange buzzing, the reason is that the ESP is at the limit voltage for operation, but I 'm not sure this is your case.

Same buzzing here…

… and it was middle in the night on full volume!!!111111 holy crap!
As i write this it happened five times on different days to different times. Really strange and annoying!

Could it be if it is losing wifi or if it is reconnecting wifi?

EDIT: It seems that the disconnection is the issue. Every sensor/button in HomeAssistant was N/A at the moment of the buzzing.

I’ll try a different powersupply maybe there is a peak in power consumption or something.

ok will setup one speaker here in the office and let it run until it happens, there is no reason not to find the bug, it might be some kind of software crash + the enable amp pin at 1 while it happens :thinking:

This also happens to me all the time. Mine is normally plugged in when it happens and I believe the cause is when the esp restarts. An easy way I can trigger it is when I do an OTA esphome update to a newer version. It happens every time I do that. Next time I’ll do that when it’s only on battery to see if it happens then too or not.


Hey, where can I get the Squeezelite logs?
I really like to help. Cause at this point I cannot use it in my home.

also happens to my Muse Luxe.
Every time the ESP crashes and reboots, volume is at 100% and a loud pop/crack is heard. Very annoying. I mapped in my Home Assistant 6 buttons with 6 Radio streams. 1 stream was alway working fine, but every time I start that radio stream the ESP crashes and reboots with the annoying pop/crack and loud volume at 100%. Indeed ESP32 crashes, I can see Home Assisant ESPHome sensors falling off.

I would describe it as a loud static burst, but my Muse Luxe is doing the same thing on software reboots with the squeezelite firmware. Doesn’t seem to happen on a physical power down/power on but only during resets/reboots. Is there a way to enforce a mute until the reboot process is complete?

Burst is heard as reported by others for example if the firmware is updated via esphome. However it repeatedly happens using Radio Browser integration on Home Assistant. At changing radio stations once a station does not play, then I hear the loud burst. It is a pity, since the device was supposed to complete the music box project for kids and be my internet radio once kids are not around. It has to be sent back to Amazon until a solid fix is implemented.
Muse Luxe, installed raspiaudio-muse-luxe.yaml by esphome.

I have tested it here and with the radio browser it seems that MP3 radios work fine and some others like “FIP” that streams in AAC make it crashe! is it the same for you?

Can confirm that this horrible noise is happening playing / trying to stream AAC streams, yes.

Same over here. Horrible → my wife won’t let me use ‘the thing’ again.

Hi Northalpha,
May I ask why you don’t use the Squeezelite firmware + the Slim device integration in Home Assistant? it seems more stable to me.

Hello, I am getting exactly the same issue as soon as the battery is getting low.

@Raspiaudio: Can you help me/us somehow?

Since this issue doesn’t look solvable, I am tending to send the device back.
If I don’t find a solution within the next week, the device will go back.

Many thanks to all contributions !!

BTW: Within a few days only we already woke up three times. First we did not understand what’s causing the issue ?!?

same problem for me with the media-player yaml

I buyed 5x muse luxe, i hope i will not need to return them :x
(crosspost : Muse Luxe voice assistant now possible? - #8 by dapsaille)

With the upcoming HA voice assistant update, i have no doubt that the muse luxe will become a must have ^^, i hope it will handle that role.

Sorry, I have sent the device back now since there was no solution in time. Many thanks to all who helped!! regards, red
