general/other no audio in a debootstrap chroot env

W

wismos

hey there, everyone i followed the linuxulator docs to setup the debootstrap env and have mounted everything fine in the fstab but after setting up xorg and gui stuff, whenever i run a gui app that has sound inside the chroot the app launches fine but there is no audio with the following logs in the terminal

ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5180:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory

any help would be really appreciated, thanks
 
I don't remember how i did it at the time i tried to run linux app in a linux jail but i think you should make your host and guest (linux jail) use the same pulseaudio socket (?). IIRC, i was exporting a variable in guest according to host's pactl info and then running the app i am trying to get sound from. maybe it was $PULSE_SERVER.

pulseaudio(1)

Code: 
       $PULSE_SERVER: the server string specifying the server to connect to
       when a client asks for a sound server connection and doesn't explicitly
       ask for a specific server. The server string is a list of server
       addresses separated by whitespace which are tried in turn. A server
       address consists of an optional address type specifier (unix:, tcp:,
       tcp4:, tcp6:), followed by a path or host address. A host address may
       include an optional port number. A server address may be prefixed by a
       string enclosed in {}. In this case the following server address is
       ignored unless the prefix string equals the local hostname or the
       machine id (/etc/machine-id).
 
hi mate

from memory the /tmp directory should be mounted from the host to the chroot

then all you have to do is this

on freebsd

Code: 
~/.config/pulse/default.pa

Code: 
#!/usr/local/bin/pulseaudio -nF

# include default.pa and override
.include /usr/local/etc/pulse/default.pa

# pulseaudio socket
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif
load-module module-native-protocol-unix socket=/tmp/pulseaudio.socket

in the chroot

Code: 
~/.config/pulse/client.conf

Code: 
default-server = /tmp/pulseaudio.socket

then start pulseuaudio on freebsd

Code: 
pulseaudio --start --daemonize 2>/dev/null

i have done that as per the linuxulator docs
all the chroot related mounts in /etc/fstab are

devfs /compat/audio/dev devfs rw,late 0 0
tmpfs /compat/audio/dev/shm tmpfs rw,late,size=1g,mode=1777 0 0
fdescfs /compat/audio/dev/fd fdescfs rw,late,linrdlnk 0 0
linprocfs /compat/audio/proc linprocfs rw,late 0 0
linsysfs /compat/audio/sys linsysfs rw,late 0 0
/tmp /compat/audio/tmp nullfs rw,late 0 0
/home /compat/audio/home nullfs rw,late 0 0

where /compat/audio is the chroot env

this file doesn't exist on my system but /usr/local/bin/pulseaudio does and the .config/pulse dir has some other files as well
so should i create this file manually?

sorry if it is a noob question that i shouldn't ask but i am not familiar with pulseaudio so i need to ask are these shell commands or some script lines?
 
hi mate

use mkdir to create the pulse directory in your home/.config
if it doesnt exist

Code: 
mkdir -p ~/.config/pulse/

create the default.pa if it doesnt exist

Code: 
~/.config/pulse/default.pa

add the following code

Code: 
#!/usr/local/bin/pulseaudio -nF

# include default.pa and override
.include /usr/local/etc/pulse/default.pa

# pulseaudio socket
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif
load-module module-native-protocol-unix socket=/tmp/pulseaudio.socket
 
no

you only need to configure pulseaudio on freebsd and in the chroot

then start pulseaudio on freebsd

Code: 
pulseaudio --start --daemonize 2>/dev/null

yeah that didn't worked, and instead even the xfce pulseaudio plugin stopped working after that XD, stopped working as in it is showing the mute button and isn't detecting my audio devices but it started working again after deleting the default.pa and client file, i wonder why , anyways thanks for trying to help
