Description GroovieMan 2017-12-01 06:56:32 UTC
Description of problem:

Version-Release number of selected component (if applicable):
F26 (up to date) -- KDE/Plasma Desktop

How reproducible:
Select your sound output HDMI and start Amarok or any other musicplayer. The sound control (volume) reacts slow and slower and the output on the monitor gets more an more distorted.
Switching back to internal audio gives you a clear sound and the responsiveness of the volume control is back.

Steps to Reproduce:
1. select hdmi/dp as you output
2. start you music player
3. wait a minute, controls getting slower and more and more distortion comes out of you monitor speaker

Actual results:
output via HMDI/DP cannot be used ;-/

Expected results:
Same quality not distorted sound

If found that:

[cgroove@suggs ~]$ ps xa | grep -P 'speech-dispatcher.*\.conf'
 5393 ?        Sl     0:00 /usr/lib64/speech-dispatcher-modules/sd_espeak /etc/speech-dispatcher/modules/espeak.conf
 5398 ?        Sl     0:00 /usr/lib64/speech-dispatcher-modules/sd_dummy /etc/speech-dispatcher/modules/dummy.conf
 5401 ?        Sl     0:00 /usr/lib64/speech-dispatcher-modules/sd_cicero /etc/speech-dispatcher/modules/cicero.conf

 6041 pts/2    S+     0:00 grep --color=auto -P speech-dispatcher.*\.conf


[cgroove@suggs ~]$ killall speech-dispatcher

kills the distortion!

[cgroove@suggs ~]$ rpm -q -f /usr/lib64/speech-dispatcher-modules/sd_espeak

Hups whats this ?

I have the same issue on Fedora 27 *and* 28, except it happens with normal audio jack output.  No need for HDMI / DisplayPort audio.

Killing the speech-dispatcher processes immediately clears up the (very severe in my case) audio distortion, and disabling auto-spawn in /etc/speech-dispatcher/speechd.conf fixes it permanently.

Comment 3 Fedora End Of Life 2018-05-03 07:56:25 UTC
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 4 Daniel Alley 2018-05-09 17:57:47 UTC
I'm not familiar enough with the audio architecture of Fedora to understand whether the issue is truly speech dispatcher or something else, so if this issue should be closed and a new one opened, (or just rename this one), that is fine.

Comment 5 GroovieMan 2018-05-09 21:22:35 UTC
Sad to say that the problem still occur in F27, possibly also in F28 (gonna check it)
