Thanks. You clarified the whole thing enormously. My system is now working. No need for me to post results. They showed the several issues were as they should be. Your replacement last step using speaker-test, at first, produced no sound. This lead me to question my 'make sure the speakers are turned on' action. A careful inspection the the rear of my compute, in a better light, lead me to discover the cable plug on the back of the computer was plugged into the microphone input hole, not the line-out hole. Once the plug got into the correct socket, things worked just fine. Since you are intending to patch the last bullet point in the release note, I suggest that you also recast the other bullet points where you suggest specific commands to type and the specific results to be expected. Its OK, even good, to keep a higher level explanation of what issue the specific command/result will address, but it is really helpful to a confused non-expert to be told specifically what to do and what result to expect (as you have already done for me) Note: man speaker-test, in English, refers to the default wave form as pink noise. but says "Pink noise is perceptually uniform noise -- that is, it sounds like every frequency at once.If you can hear any tone it may indicate resonances in your speaker system or room." Why pink? Why not blue, or green, or - white? I doubt that the term has a serious technical definition in telecommunications theory, which is the technological origin of ideas of noise. I would call it the sound of radio receiver static, but modern radio receivers have inter-station noise blanking, so this suggestion is an indication of my advanced age. Or, the sound of wind in a forest. Or, the sound of wind in a desert. You may be able to avoid discussions with pedants like me about word descriptions of the sound of noise by suggesting the test be speaker-test -c2 -t wav On my computer with my locale settings this gives a woman's voice repeating, until I type cntrl-C, in English, "Front Left ... Front Right " Your computer, in your locale, should have different wav files in /usr/share/sounds/alsa, and should give an equivalent sound track, but in your 'locale' language. If so, you can avoid all word description of what noise sounds like in different cultures.
