Linux Operating System KNOPPIX 7.7 connect to Bluetooth Speaker how-to_ INTEL DZ68DB Motherboard

After installation of Linux Operating System KNOPPIX 7.7 on a  32 GB  USB Flashdrive  using a Linux  OS  Live Distro of Linux Operating System KNOPPIX 7.7  on an  ACER Aspire R15  Laptop which is connected to a  PHILIPS 32 inch  HDMI  TV . 



1.   Connect the ACER Aspire R15 Laptop to a  PHILIPS 32 inch HDMI  TV ( used this as a  PC/Laptop  Monitor ) using HDMI cable , then , insert the the  32 GB USB Flashdrive onto the USB port ( preferably USB 2.0 port which is located on the right hand side of the Laptop ) of the ACER Aspire R15  Laptop .  Then , boot up the Linux OS KNOPPIX  7.7 using the  32 GB  Flash drive with the Cheat Code  knoppix64  xmodule=svga  screen=1360x768  .  ( type the Cheat Code on the keyboard ) . The  reason for this cheat code , so that I can get a  screen resolution of  1360x768  on my  PHILIPS  32 inch HDMI  TV and the screen resolution of 1360x768 on my  ACER Aspire R15  Laptop .  After the  Linux OS KNOPPIX 7.7  is fully booted up , then ,   run the Linux Command   # apt-get install debian-archive-keyring , then ,   run the  Linux  command  # apt-get install update .

2.   Use Synaptic Package Manager  and search for "firefox" , then install ( Mark for Complete Removal the old version of Firefox , which is ,  firefox Version 49 )   "firefox Version 68"   using Synaptic Package Manager .
Also , using  Synaptic Package Manager  ,  please search for "chromium"  and upgrade (Mark for Upgrade )  Chromium web  browser from Chromium Version 53  to  Chromium Version 83
Upgrading Chromium Web Browser  from Chromium Version  53 to  Chromium Version 83 will ensure that sound or audio coming out from YouTube ( running under Chromium Version 83 )  is functioning .

3.   Then , use Synaptic Package Manager to install the software packages  below :

      1.   alsamixer .  For Linux OS KNOPPIX 7.7  , the software package is  "alsa-utils"  and   "alsamixergui" . If these two packages are already there , just leave it as it is . 

      2.   pulseaudio

      3.   pulseaudio-module-jack

      4.   pulseaudio-module-bluetooth

      5.   pavucontrol .  Installation of  'pavucontrol'  software take a slightly longer time to complete , so , be patient .

      6.   blueman




4.   Then , open up Firefox web browser (Version 68) and play YouTube . No audio or no sound coming out from the 32 inch HDMI Monitor .


5.   Then , open up  "PulseAudio Volume Control"  and we get this ,  displayed on the  Monitor . 


6.   Then , open up  "LXTerminal"  and run the Linux command
       $ pulseaudio --start


7.   Then , we get this , displayed on the Monitor .


8.   Then , go to Internet and Click  "Firefox ESR" and play YouTube videos , you still cannot hear any sound or audio coming out from the speakers , either from the PC/Laptop or  PHILIPS 32 inch HDMI  TV .

10.  Then , once again , go to Internet and Click  "Firefox ESR" and play YouTube videos , you still cannot hear any sound or audio coming out from the speakers , either from the PC/Laptop or  PHILIPS 32 inch HDMI  TV .


11.  Then , go to PulseAudio Volume Control icon and Click  "PulseAudio Volume Control"  and maximize it and we can see the  Firefox AudioIPC Server  "horizontal bar"  fluctuate from left to right , telling us that  a  YouTubeVideo is being played on Firefox , but still we cannot hear any sound or audio coming out from the speakers , either from the PC/Laptop or  PHILIPS 32 inch HDMI  TV .  [ 1 ]


12.  Then , on the  Firefox AudioIPC Server , on the right-hand corner there is a rectangular box and  Clicking  the  "Built-in Audio Digital Stereo(IEC958)" , give us two options . We can either choose  "Built-in Audio Digital Stereo(IEC958)"  or  "Cedar HDMI Audio [Radeon HD5400/6300 Series] Digital Stereo(HDMI)" .  If we have a Speaker that is connected to the Headphone Speaker port on the  PC/Laptop ,  then  Select    "Built-in Audio Digital Stereo(IEC958)"  but if we want the sound or audio to come out from the  Speaker of the   PHILIPS 32 inch HDMI  TV , then  Select   "Cedar HDMI Audio [Radeon HD5400/6300 Series] Digital Stereo(HDMI)" .  


13.  CONNECTING TO A  BLUETOOTH SPEAKER .  Minimize the  PulseAudio Volume Control   GUI .


14.  Then , open up  "LXTerminal"  and go to  SU mode (super user mode)  and run the Linux command  # blueman-manager  to get a Blueman GUI ( Graphical User Interface ) so that we can use this Blueman GUI to connect to any Bluetooth devices .


15.  After getting the  Blueman icon , Click  "Search" to scan for any Bluetooth devices nearby . Then after getting the Bluetooth device that you wish to connect  to , in this case ,  the  Bluetooth Speaker  is  "PhilipsBT" , then Click that particular Bluetooth Speaker which is called  "PhilipsBT" .
Then ,  Click   "pair"  then  "trusr"   then  "Audio Sink"  .  After that 3 colourful (orange/light green/blue) vertical bars  will appear on the right-most corner of the Blueman GUI .  The 3 colourful vertical bars will stay  "on"  continuously . Please note that if the 3 colourful vertical bars stays  "on"  for a while and then  "goes off" .
That mean something is not right .




16.   Then , once again , go to Internet and Click  "Firefox ESR" and play YouTube videos , you still cannot hear any sound or audio coming out from the Bluetooth Speaker , which we stream from the PC/Laptop using Linux Operating System KNOPPIX  7.7


17.  Then , go  "PulseAudio Volume Control"  GUI  and maximize it and we can see the  Firefox AudioIPC Server  "horizontal bar"  fluctuate from left to right , telling us that  a  YouTubeVideo is being played on Firefox ESR , but still we cannot hear any sound or audio coming out from the Bluetooth Speaker , which we stream from the PC/Laptop .


18.  Then , on the  Firefox AudioIPC Server , on the right-hand corner there is a rectangular box and  Clicking  the  "Built-in Audio Digital Stereo(IEC958)" , give us  three  options . We can either choose  "Built-in Audio Digital Stereo(IEC958)"  or  "Cedar HDMI Audio [Radeon HD5400/6300 Series] Digital Stereo(HDMI)"  or  "PhilipsBT" .  If we have a Speaker that is connected to the Headphone Speaker port on the  PC/Laptop ,  then  Select    "Built-in Audio Digital Stereo(IEC958)"  but if we want the sound or audio to come out from the  Speaker of the   PHILIPS 32 inch HDMI  TV , then  Select   "Cedar HDMI Audio [Radeon HD5400/6300 Series] Digital Stereo(HDMI)" . And if we want the sound or audio to come out  from the Bluetooth Speaker , then  Select  "PhilipsBT"  [ 1 2 ]  and it should be okay . Enjoy !
