Line in on boot

[stebod]

Hi line in and mic need to be enabled manually in preferences audio device settings even after making default. I need line in to work from boot without having to go in and manually enable this setting, i have entered alsactl --file /usr/share/doc/audioInjector/asound.state.RCA.thru.test restore but nothing changed, every time i switch on or restart i have to tick the line in box to enable it

It is likely that this has something to do with the Pi's operating system "lxpanel" software. In the past we have noticed lxpanel obliterating .asoundrc files :
https://github.com/raspberrypi-ui/lxpanel/issues/13

That thread suggests that there are plugins which are operating which override the standard ALSA mode of operation. I am cross linking this thread to that thread to see if we can get more advice from them.

I am wondering if lxpanel also messes with mixer settings obliterating standard alsactl methodologies ?

I have logged an issue with lxpanel asking for help.

Good Day All,

I had the same problem at first.

I discovered if I set Line through the alsamixer, followed by:

Code: Select all

sudo alsactl store

everything stayed set to line in.

Hope that helps.

Hey Matt after reading the replies do you think there can be fix for this or possible work around ?

Can you give IrwinAllen13's approach a test again ?
I think it will be messed up when you change something in the lxpanel volume plugin (top right volume icon) although I could be mistaken.

Otherwise we have to learn how to remove the volume plugin from lxpanel ... and possibly other things - what do you think ?

I will try that and post the results

Since installing pulseAudio because of the little endian script problem i cant get into alsamixer

pi@raspberrypi:~ $ alsamixer
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Access denied

cannot open mixer: Connection refused

ok - that is a strange problem !

I have been disabling the lxpanel's volume control like so :

Code: Select all

sed -i 's/\=volumealsa/\=REMOVEvolumealsa/' ~pi/.config/lxpanel/LXDE-pi/panels/panel

I also uninstall pulseaudio:

Code: Select all

sudo apt remove pulseaudio

can you check your device is present ? Does aplay -l report it ?
