Ok so had a sleep and the question is.....at post 7 you changed the system wide config to 6 channels and made no other changes to system wide configs
--------but can not get 6 ch until you remove the PA run files.....why?

I am clueless at this stage.

so let us try instead to disable PA, when you are ready to try....see if alsa is good enough to give you surround sound and then (and only then) make PA fail on reboot.

Please keep my downloads somewhere safe in case we need to restore them

step one
change PA so it will not autospawn(= restart)

use root powered kwrite to edit /etc/client.conf to edit these 2 lines
autospawn = yes
allow-autospawn-for-root = yes

so they read
autospawn = no
allow-autospawn-for-root = no

step two
stop PA

step three
test PA is not running.

I prefer you open a terminal and run htop -> press F3 to search and input pulseaudio

but a quick and dirty way without installing htop (if slackware does not have it) is this

you will get no output if it is NOT running....simply close the terminal or press CTRL and c keys to close the command.

step four
check alsamixer is showing 6 ch....if not redo the alsamixer restore command from earlier posts

step five
play a surround file to test your sony speakers

if this works....I will give steps to disable PA over reboot..but I will wait to see if you understand my suggestions

to any slacker lurking this post.

I looked at the contents of /etc/rc.d/rc.pulseaudio and saw this line

but on a ubuntu based system that executable is not under bin but /usr/bin

If you agree, slack uses /usr/bin too....maybe someone can tell the slack build maintainer?

I downloaded the txz file from here
http://ftp.iinet.net.au/linux/slackw...2/slackware/l/

It is located in /bin/

Since you were willing to dig into the package, you can also use the Slackware Package Browser at http://packages.slackware.com

You can search for individual files changing the "Mode" dropdown to "Content". You can then search for individual files, and it'll let you know where they are at in the filesystem.

thanks bassmadrigal

If you or others that have contributed to this post......what do you make of my question at top of post 31.

ie OP has made only one change to a system wide PA config file but appears to need to delete the PA run files to make it work even over a reboot shutdown etc.

optional (2) do you agree that Slackware can safely run without PA?

once OP says....hopefully alsa runs with surrround sound 5.1 (6 ch) I plan to ask him to remove the executable to the etc/rc.d/rc.pulseaudio file

Hello, aus9,
as I wrote in post #25, I was actually contented with my sound at the current stage. It seems to me to be a surround sound with high quality. I am simply curious with respect to the testing of the system in the KDE settings when the dual stereo switch of the SONY control device is "on". I am not sure I am motivated enough to go into all the trouble with disabling PA, which is already notorious in this forum.

Hi in post 25 you said you needed to delete stuff. Are you still needing to do that?

If no then happy for you to mark as solved.

Hello,
I only needed to delete stuff once, and now things work normally after reboot. Unless you think the behaviour I described in post #25 (I provide it below for convenience) is not OK, I can mark this thread as solved.

I am on KDE but I use pavucontrol. So personally the big picture now that you said you only needed to delete it once....mark as solved please.

Many thanks to all the people who contributed to the solution of this problem, in particular to aus9,
who led the process to the end.
