Description George Kraft 2005-06-17 08:36:37 UTC

Distribution: Fedora Core 4
Hardware Environment: ThinkPad T30
Software Environment: gnome 2.10.1
Problem Description: ALSA has just released version 1.0.9a which fixes their
eight month old bug #557 which caused sound clipping for accessibility text to
speech.

Steps to reproduce:

1. Install ibmtts (aka viavoice)
2. automake gnome-speech
3. run "test-speech"

Actual Results:  test-speech will chop off the end of spoken text.  Festival
will not work out of the box for a different reason, so ibmtts is used in this
example.

Expected Results:  test-speech should complete its spoken text.

See SNDCTL_DSP_GETOPTR in ALSA 1.0.9a change log.

I don't understand.  Are you saying that ALSA 1.0.9a fixes a bug which is in
2.6.11 and should be merged?  Or are you saying that 1.0.9a introduces a new
bug, or what?

It's unclear what action kernel maintainers need to take...

There was an accessibility bug reported in ALSA eight months ago.  It was
recently  fixed in ALSA 1.0.9a.  Red Hat will not uplift Fedora Core 4 to the
latest ALSA code until kernel.org does.

A fixed ALSA is already present in kernel 2.6.13-rc4.
