[SOLVED] Fedora 35+KDE, autostart: can't "pw-play" WAV file, from terminal

kaza · 05-07-2022, 01:30 AM

Hello!

After installing Fedora 35 I attempted to add in the "autostart" actions
the command "pw-play /path_to_file/startup_sound.wav" but for some reason, it doesn't
play at startup. If I issue the same command in a konsole - it plays OK.

What's the difference between using "pw-play" as autostart program to run
and using it in a normal command line way?

TIA!

until you get a better reply, autoplay sound for me works in IceWM on debian, without a sleep as I use alsa only

please post the full contents of your autostart file.

Leaping ahead....you may need a sleep command if you pulseaudio is involved in setting up your sound.

If you have some kind of if-then needing bash, change sh to bash, but I do not use KDE so not sure what format you need

also aplay is capable of wav playbacks so try that, it might be that simple?

eg

Quote:

!#/bin/sh
SNIP

/bin/sleep 5 &
aplay /home/myname/mp3/samples/sample.wav &

SNIP

Hi aus9, thanks for the reply.

I changed "pw-play" to "aplay", with or without "sleep 5" - same thing.

Here're the contents of that particular autostart file:

Code:

<fedora>.../autostart>pwd
/home/user/.config/autostart
<fedora>.../autostart>cat aplay.desktop
[Desktop Entry]

Exec=sleep 5; /usr/bin/aplay /home/user/sounds/jet8.wav

Just tried with sleep 10 - same result.

While reading about similar problems, someone noticed that his KDE speaker icon came "muted" and after few seconds became "unmuted".
After reading this I re-booted while looked at the speaker icon - on my KDE too, it first came "muted" and after 1-2 seconds became "unmuted".

So, here's some more info for those who understand (me not among them, at least now).

TIA,
kaza.

Please delete all empty entries from your .desktop file.
Not sure it matters, but I've never seen it like that, and it's pointless.
Also I'm not sure you can put shell commands in your Exec line like that; better create a mini script and Exec that.

Solved!

If the "sleep" and "aplay" commands will become a shell command with an argument of starting a command
then this command can contain the two parts of "sleep" and "aplay". Currently the "sleep" is 15 seconds
and the sound appears about 2-3 seconds after the speaker icon changes from "mute" to "normal",
which means: F35+KDW+Xwayland takes about 12-13 seconds to start everything and to enable the sound.

Thanks for all the replies!

well you may be happy, but maybe you should try a different desktop?

if you choose something non-KDE you will not have Phonon possible interference

try Xfce if you have not yet tried it.
