Message-ID: <01a301c3203d$6debf520$3700a8c0@jono> (raw)
Here is the output for stream0 and 1 using alsa 0.9.3c and 0.9.0rc5. The
front panel midi jacks work with version 0.9.3c but not version 0.9.0rc5.
Audio output does not work (properly) for 0.9.3c, upon sending a signal one
just hears digital noise. However with 0.9.0rc5 audio seems to work fine,
sounds files play correctly. As I said in a previous email to the list,
audio output is either silent of one simply hears digital noise on drivers
later than 0.9.0rc5.
