----------------------------------------------------------------------
The reason of not hearing any sound from the front speakers of au8830 using
alsa-plugin - jack is due to front and rear swap bug in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1726
It will also need the fix in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1766 for jackd to open
the correct
capture channels of au8830
It seem that snd_pcm_hw_params_get_channels_max() return max_channels
10000 for "plug:jack"
----------------------------------------------------------------------
Raymond - 03-23-06 16:48

If reducing the output channels to 1.
jackd -d alsa -o 1 -S
jackd 0.100.0
JACK compiled with System V SHM support.
