Subject: right way to enumerate pcm devices
Date: Tue, 12 Feb 2019 12:33:33 +0000	[thread overview]
Message-ID: <20190212123333.GB6441@freedom> (raw)

Hi,

I got some code based on hints which, unfortunately, seems not sufficient.

I can list the hardware cards, but what is the proper way to enumerate the pcm devices?

For instance, I don't get basic user defined pcm devices, I get all the
surround pcm devices for the USB mic from my webcam etc...
The real question: how I build a clean list of pcm devices I would present to a
user to choose from without confusing him/her?

Wherever I look I get only this hint based code. I presume I am looking the
wrong way.

regards,
