[SOLVED]start-up sound

Manix · 2025-05-10 11:49:43

I'd like to play a sound when my hyprland (uwsm) session starts, but if I add for example exec-once = paplay ~/Downloads/my_sounds.oga no sound.

if I run the same command in a shell, the sound plays (sometimes after 2 tries).

is it possible that wireplumber takes a long time to start up? if so, is it possible for it to start up right away to play the sound?

I've also noticed that when I pause a video in mpv, it takes ~ 3 seconds for the sound to resume.

wireplumber pipewire and pipewire-pulse start via sockets (I tried to start these services as a user

exec-once = mpv -ao alsa  ~/Downloads/my_sounds.oga

Though

sounds more like some powersaving (unless you play sound via bluetooth?)

mpv -ao alsa ~/Downloads/song.oga

doesn't work in a shell (not the packages I guess)

mpv -ao pulse ~Downloads.song.oga

works in shell but not at startup with exec-once.

sounds more like some powersaving (unless you play sound via bluetooth?)

I have sound on an HDMI TV.

I test this (link above) in /etc/wireplumber/wireplumber.conf and for the moment I no longer have a “latency” when resuming reading via mpv. still at startup though

if it can be useful :

I have sound on an HDMI TV.

Can you attach speakers or headphones?

Fwwi, "mpv -ao alsa" not "working" might be either because the device is occupied by pipewire already or because you're using the "wrong" alsa device (ie. it works, but plays on speakers etc - not the TV which is a different sound device [Edit: the different device being the HDMI output on the GPU, not your TV ])

works as expected with headphones!

if i've understood correctly, you're assuming that it plays sound on another hdmi port? if that's the case, i don't have anything else connected to my computer, apart from my 2 keyboard/mouse receivers.

in pavucontrol I've turned off “internal audio” I don't use it.

No, the soundcard where you're plugging the HPs and the GPUs HDMI output are two different soundcards (of sorts)
Try "mpv -ao alsa file.mp3" w/ the headphones.

Is the TV active while you're booting or only enabled by hyprland ?
You could try to play something earlier in the boot process (can be the sound of silence, https://archive.org/details/audio-silen … ter-second )

does not work ...

yes, the TV is switched on and operational.

You could try to play something earlier in the boot process (can be the sound of silence, https://archive.org/details/audio-silen … ter-second )

I tested this:

exec-once = paplay ~/Downloads/silent_1-second.mp3 && paplay Downloads/service-login.oga

and :

exec-once = paplay ~/Downloads/silent_1-second.mp3
exec-once = paplay Downloads/service-login.oga

no sound. with mpv too, no sound. very strange that it works with the headset and not directly on the TV.

I tested this:

"Way" earlier - with some systemd service wanted by the multi-user.target or so.
Apparently (as the HPs work) the latency is w/ the Tv.

Manix · 2025-05-11 15:11:27

I'm going to do without the sound on startup, but I've resolved the sound in mpv by pausing and then resuming.
thanks seth
