Need sound at restart

Pendeb · 12-05-2019, 10:39 AM

I'm trying to make the system launch sudo alsa force-reload, which seems to do the trick for me, but I don't know how.

I've had trouble with the autostart app, which seemingly ignores my shell script for running "pkexec alsa force-reload," and I'm having trouble with editing the sudoers file despite instructions on the web.

I'm running Ubuntu 18.04 "Bionic Beaver."

Code:

vim /etc/rc.local

Code:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
alsa force-reload
exit 0

Code:

chmod +x /etc/rc.local

I tried that, but I still have to manually reload alsa on reboot.

Ubuntu uses systemd and pulseaudio. Not sure it uses alsa, it might, I don't use ubuntu.

Open a terminal and run

Code:

alsamixer

, then note if all channels are unmuted. Close out of alsamixer (escape) and run

Code:

sudo alsactl store

. That sets everything and "I think" will restore on boot.

If that doesn't work, maybe someone who runs Ubuntu can chime in.

It didn't work.

Wait, let me recheck.

Pendeb · 12-05-2019, 06:18 PM

No, it didn't work.

assuming

Code:

# which $(alsa)
/usr/bin/alsa

(my system does not have an 'alsa' command though):

Code:

# cat <<EOF > /etc/systemd/system/alsa-force-reload.service
[Unit]
Description=Force reload ALSA

[Service]
ExecStart=/usr/bin/alsa force-reload

[Install]
WantedBy=multi-user.target
EOF
# systemctl enable alsa-force-reload

I'm still not getting sound on reboot.

I solved it myself.

I created a file, ~/.asoundrc containing

pcm.!default {
type hw
card 0
}

ctl.!default {
type hw
card 0
}

from https://www.alsa-project.org/wiki/Asoundrc

Thread unmarked as I'm still having problems

right what kind of problems?

also describe how exactly you want to hear sounds please....as we all have different setups and not mind readers.
Well I failed the course

eg laptop speakers and 3.5mm headphones
surround sound via various coloured holes
sound via inbuilt monitor speaker/tv

also show output of

Code:

aplay -l

generally speaking....ubuntu type distros use alsa with a front end of pulseaudio
pulseaudio...until you setup a home config....runs system wide configs from /etc/pulse

If a specific media player is "playing up".....name the media player
also name type of media extension .....eg wmv or mp4 etc
