Squeezeplay choose audio device?

[Phil Leigh]

How hard would it be to give SP the ability to choose it's audio output device on the host computer it is executing on?

All of my PC's have >1 audio device and in several cases I'd like to use the non-default device.
Nearly every audio app I've used has this basic ability. What would it take to add it to SP?

I'd take a quick look at the source, except I can't find where I can get it because the slimdevices wiki is down.

is it here?

It is, thanks.

It looks like decode_portaudio_init in squeezeplay/src/audio/decode/decode_portaudio.c is the code that picks a device, it just uses the first device that it finds that supports the format/rate it needs.

Assuming that is correct, it would be fairly straight forward for a competent c/c++ coder to add a hacky solution there to use the device id from a config file instead. Unfortunately I don't fit the description of a competent c/c++ coder.

Adding "proper" support for picking devices in the app would obviously be much harder, involving UI changes and no doubt touching multiple layers of the code.

Thanks Andy... a hacky solution would work for me :-)
I'll take a look at the code

Although that said, I can't see where decode_portaudio_init is called from, so it is entirely possible I'm barking up the wrong tree.

There's some strange code in there regarding sample rates:

decode_audio->max_rate = 48000;

Why is the max_rate capped at 48k?

[andynormancx]

Like I say, I might be barking up the wrong tree, maybe that code isn't actually used ?

You're in the right place.

There's a structure of function call pointers at the bottom. Which includes decode_portaudio_init.

The struct is then referenced in decode.c.
