Re: [Gumstix-users] Gumstix OE AudioStix2

[Steve S. <sa...@gm...>]

I found the error, silly as usual.  In /etc/asound.state:

                name 'Master Playback Switch'
                value false

Duh!  Setting it to true results in sound output.  Amazing :-)

Fix will be in revision 149.

Still some issues with init ordering -- seems to want to be loaded
after bluetooth init.  Will fix after more debugging.
