Multiple sound inputs to one stereo (sound mixing) how do you handle it?

Hardware
1

I have integrated 2 chromecast audios into my HA setup.

The issue I have is that I only have one input on my stereos and I always end up having to manually unplug my chromecast to plug my other input in (for example my TV) This is not idea when I want to use my chromecasts for notifications :slight_smile:

How does everyone else deal with this?

I would either buy a separate speaker for the notifications or a amp that you can switch inputs with either IR or network commands. CC Audios are meant to be added to speakers :slight_smile: Not sure if this really helps you tho’ :stuck_out_tongue:

I have two pi’s analogue outputs connected to one amp input using a y connector 3.5mm.

4

What happens when they are both playing?

5

I hear them both, one has TTS for HA and the other i have shairport which I don’t use that much.

6

Neat solution :slight_smile:

7

Did you buy one of these cables or did you make it up yourself?

8

Its kind of the path i have gone down :slight_smile: not exactly happy with it though.

I use two pi’s with HA, one for TTS mainly and the other pi for music. This is the only solution I could think of without having to switch inputs on the amp. I use two pi’s so I didn’t have to switch audio application on the pi which caused problems.

I use a switchable audio input kit and an esp8266 to do “automatic” swicthing via MQTT for inputs to my stereo.

The stereo does not have a remote, so I just switch using MQTT between CCA, squeezebox, other

It was a bit of fiddling to setup the kit, but now I have automations to switch source to CCA if it starts playing (ie a TTS), switch to squeezebox if it is playing, otherwise stay on the other channel (which is old school phono!)

Thats pretty elegant but almost getting into this sort of money :slight_smile:

I bought one of these to test :slight_smile:

Except the model you linked is manual switching. Using the relay based unit allows for machine switching by HASS (or something else)

15

Correct me if I am wrong but as a sound mixer, it should just “mix” the sound together so no manual switching would be required?

ahh - fair dues … just re-read the title!

I like your idea but it sounds like quite a lot of time to set it up.
