I have two outputs?! Headphones and speakers... :sound_out

[jonny]

Windows 11 has the ability to map apps to devices
(although I’m struggling to find the option to toggle device-mixer that I thought I had, maybe on win 10, with a volume slider per app, and a dropdown to switch device, in a classic control panel, IIRC)

With SonicPi, due to SuperCollider, an application restart is required after a hardware change, like plugging in headphones.

If you do this:

1. open sonicpi, play a sample (on speakers, no headphones in)
2. plug in headphones, go to sounds, make noises using headphones (in other windows apps, or volume-slider at least)
3. go back to sonic-pi, and the sounds are still playing.

This is a bit of a revelation as years ago on windows 7 I’d tried to do this, but thought “it’s just one audiobus”.

I’ve tried to make the :sound_out work, but I think the audio_settings need to be configured.

Looking at the sound device properties they have friendly names like “Speakers” and “Headphones”

and both have the same controller info

Can I target Speakers / Headphones using :sound_out ?

Conversely, the “other” audio device in my laptop (device manager) is the Intel Display Audio.

audio-settings.toml

Previously I tried to do the same switching / setting output to my bluetooth headphones, but that didn’t work

Currently I have these settings (Just increased num_outputs to 4, but now no sound out):

sound_card_name = "Conexant ISST Audio"
sound_card_sample_rate = 48000
sound_card_buffer_size = 64
# num_inputs = 16
 num_outputs = 4

The Hardware ID’s listed from devmgmt are

INTELAUDIO\FUNC_01&VEN_14F1&DEV_50F4&SUBSYS_103C80FD&REV_1001
INTELAUDIO\FUNC_01&VEN_14F1&DEV_50F4&SUBSYS_103C80FD

Compatible ID’s

INTELAUDIO\FUNC_01&VEN_14F1&DEV_50F4&REV_1001
INTELAUDIO\FUNC_01&VEN_14F1&DEV_50F4
INTELAUDIO\FUNC_01&VEN_14F1
INTELAUDIO\FUNC_01

Hopefully a) this is achievable and b) that’s enough info!

Progress: Found another user troubleshooting similar query whilst searching for audio-settings.toml, they were struggling with the names to use too - looks like I guessed that bit right

Checking prefs with my mentioned settings the requested samplerate is seen, and a device matching the name provided is set on input and output

commenting out my soundcard settings and restarting the defaults are seen

Reviewing %userprofile%\.sonic-pi\log\scsynth.log I find device id’s
etc…

Can different devices be targetted with :sound_out or any other sonic_pi method (command/synth/fx/config) ?

Thanks to the link mentioned by @ethancrawford (on GH) I see this is a question about aggregate devices, the common solution on windows is ASIO4ALL

Aggregate device

Audio device selection | SuperCollider 3.12.2 Help (sccode.org)

Sometimes you might want to use multiple devices for input or output. macOS provides a way to combine multiple physical devices into a virtual Aggregate Device. To create one, you have to open the Audio MIDI Setup application (in /Applications/Utilities). You should do this from an user account with administrator privileges.

Testing with flexaudio (recommended elsewhere) … stumped. thwarted. sigh.

Maybe with a Mac, apparrently not even with VAC.

Suspect this may not be possible, for reasons not yet known.

In ASIO4ALL I can configure both outputs

Adding sound_card_name = "ASIO4ALL" to audio-settings.toml and then launching sonicpi, the log suggests the config may work

Device options (4 outs shown, previously only 2):
- ASIO : ASIO4ALL v2 (device #16 with 2 ins 4 outs)

I was just about to confirm same issue, only headphones sound… but I’ve just given myself my second biggest sonic-pi-shock to date, when test succeeded, and :glitch_bass_g came blasting out stereo: 3 .

I think we have reached a milestone!

Resting Retesting!..

test success as
