Beagleboard and kernel 3.2.3-x4 problems

[Karl Lattimer]

Hi all,
I have recently just set up a beagle board (xm rev c) using the
guide here; http://elinux.org/BeagleBoardUbuntu and after managing to
get a working DSP with release 4 (kernel 3.2.2-x4) I discovered that
the omaplfb.ko driver was missing and therefore had no video, a brief
chat with Robert Nelson and I managed to get it working.

For the record I'm not running a desktop session, I just want to be
able to run a player app on an X server.

With this latest r5 release and kernel 3.2.3 I'm getting errors like
the following;

I thought I suggested to run 'gst-launch audiotestsrc ! autoaudiosink'
and you said that didn't work, so the issue is not related to gst-dsp.

Most likely the problem is related to ALSA, so I would look at the
differences between the 3.2.2 and 3.2.3 kernels on the sound/soc area.
You could try 'gst-launch audiotestsrc ! alsasink' , and if that
fails, try aplay, or some ALSA based test. You should discuss this
with Ubuntu maintainers I guess.

The other possibility is that there's something wrong with
autoaudiosink (in case alsasink works), but that should not depend on
the kernel version, and you should contact the GStreamer mailing list
for that.

Cheers.

I don't know anything about jackd, but it seems that the jack daemon isn't
running.

I guess is like pulseaudio.

Why don't you drop that and use alsa directly?

My guess is that alsasink fails first, and then jacksink is tried,
which also fails.

Alsa seems to work as I finally got it running. Thing is I need jackd running for sound to work it seems... Not ideal, also it isn't particularly reliable, but I guess I should expect that with a newer kernel.

Thanks anyway,

K,

I don't think you need jackd. You probably should use alsasink and try
to figure out what broke it.

Cheers.
