Stephen's questions

I edited the /etc/pulse/daemon.conf to make it 6:

stephen@stephen-Aspire-TC-605:~/$ cat /etc/pulse/daemon.conf | grep channel
; remixing-use-all-sink-channels = yes
default-sample-channels = 6
; default-channel-map = front-left,front-right

after restarting I still get only stereo in the sound settings. installed the pavucontrol and still nothing. the 5.1 is connected with three jacks on the back, not hdmi. Something is missing

tephen@stephen-Aspire-TC-605:~$ speaker-test -Dplug:surround51 -c6 -l1 -twav

speaker-test 1.2.2

Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Playback open error: -2,No such file or directory
tephen@stephen-Aspire-TC-605:~$ aplay -L |grep 5.*1
surround51
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround51:CARD=PCH,DEV=0
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers

... with many rows about hdmi, dmix and dsnoop

I have a 16gb card in my laptop running Lubuntu 18.04, which is formatted as swap. when I click on activate partition in Disks I get this error:

while the partition is recognized as swap by the app

on ubuntu 14.04 forefox won't play swf even though flash is installed. I tried editing the mime type file and updated the mime databse and still get nothing.
