Hi, FWIW: while developing a GSTreamer presentation using a BegleBoard (revC), I noticed the same "tuck" sound. It also occurs a second or twoafter the GST application exits. I assumed it was some power managementcode that was disabling the audio codec after it had gone idle, butnever looked into it. BeagleBoard also uses TWL4030. GST command: gst-launch audiotestsrc freq=1000 num-buffers=100 !alsasink /proc/version: Linux version 2.6.28-omap1 (ddompe@Aleph) (gcc version4.3.1 (GCC) ) #2 Thu Mar 5 08:55:58 CST 2009 Code image: http://www.beagleboard.org/~arago/esc/esc2009sj.v12.img.gz Todd On Wed, 2009-05-06 at 19:30 +0530, Aggarwal, Anuj wrote: > > -----Original Message-----> > From: Peter Ujfalusi [mailto:peter.ujfalusi@xxxxxxxxx]> > Sent: Wednesday, May 06, 2009 11:03 AM> > To: Aggarwal, Anuj> > Cc: linux-omap@xxxxxxxxxxxxxxx; alsa-devel@xxxxxxxxxxxxxxxx> > Subject: Re: Beep sound in the end of audio file> > > > Hello,> > > > On Tuesday 05 May 2009 20:03:57 ext Aggarwal, Anuj wrote:> > > Hi,> > >> > > After playing out any audio file on OMAP3 EVM, having TWL4030 codec,> > > I am hearing a beep sound.
