Describe the issue

I got Android phone and I connect it to car with USB. Android auto start to auto play what ever I was playing last time when connected. Sometimes I however get issues with this. Arc seems to start to play song, but no audio comes out to car audio system. I see track time going forward like it would play. It do not help to start and stop it. Disconnect and reconnect works, but sometimes I need to do it multiple times.
Other audio trough android auto works at the same time... Like map software directions.

Describe your network setup

Home I got 1Gb fiber Internet and home network got 1 Gb switch with CAT6 cables. Phone is connected with 5g usually with full connection.

Hello @Jesse_Lahtela,

Don’t know exactly it is Mitsubishi Outlander PHEV

No. Only Roon Arc.

This happens to to time and I cannot reproduce it by will.
I can’t remember exact time, but last time it did happen on Friday 18th at morning time (EEST).

Hi @Jesse_Lahtela,

Thanks for the update - just to confirm, the only audio issues you have are based around the auto-start mechanism within Android Auto, correct?

Have you investigated any settings to temporarily disable the auto-start function?

Do you have the below setting option?

  • On your Android phone, go to Settings > Connected devices > Connection preferences > Android Auto
  • Scroll down to Start Android Auto automatically
  • Set it to “If used on the last drive” or “Always ask”

If you do, I’d be curious to see if you continue to experience issues. On the vehicle side, some vehicles have a setting to disable Android Auto auto-launch or connection behavior:

Check your car’s infotainment system settings for something like:

  • Start Android Auto automatically
  • Projection settings
  • Phone projection preferences
  • Then set it to Manual launch only

Let me know if either helps! :raised_hands:

Can’t really confirm that. I have just noticed it always as “auto-start” have been enabled and then audio do not play… or well it looks like it plays, but no sound.
As well it do not help if I stop play and then start it again.

I do have this and I will test.
However please note that I cannot replicate issue at will… I would say it happens like 1 out of 10 times or even more rare.
As well I do not drive daily… so it may take a while to validate did this actually help or not.

Need to check this one, but I think I do not have this kind of settings on my car.

Sounds good @Jesse_Lahtela, keep up in the loop when you’re able to give it a go! :+1:

This have not happened so far again to me.
But I have only driven several times since my last message.

Will followup later.

Hi @Jesse_Lahtela,
No problem. Take as much time as you need to test!

Hi, this issue happen me again. Automatically start play was not enabled.
Once I pushed play on player “time numbers” started to run but no audio.
Audio device was correctly selected on car. It does as well automatically switch what it did, but no audio…

Took screenshot, but it do not tell much as no any error is displayed…


Basically number where running and “progress bar” was moving.
