ALSA license

ALSA license

[Li, Steve]

I am trying to use ALSA in a commercial application. I see that in the introduction page, ALSA is licensed under GPL and LGPL. Can you tell me which part of ALSA is licensed under LGPL? What is the best way to find out this information?

Thanks
Steve

It's just reading license information included in each software packages 
(in most cases COPYRIGHT file). Under ALSA project, several softwares 
are developed. Which softwares do you plan to use?

Thanks for your response. My goal is to implement audio playback in my application. The input is PCM audio buffers. I will also need to query the timing information so that I can synchronize the playback with video.

I am just starting to look at ALSA. I'd appreciate if you can point me to the software that I need. I am trying to check the license information before I start my development.
 
Thanks
Steve

The ALSA library itself is licensed under the LGPL, so your closed-
source application can link to libasound.so.2.  Other parts of ALSA
(kernel drivers, plugins, etc.) are GPL.
