<div dir="ltr">Hi Jason,<br><br><div class="gmail_extra"><span class="gmail-"></span><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><span class="gmail-">
</span>Step 1 is refreshing the Pulse install. Seems sensible.<br></blockquote><div><br></div><div>That is what I thought.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Step 2 is....what now? WTF does Terminal scrolling history got to do with sound?<br></blockquote><div><br></div><div>Nothing directly but having run the script on a box I DON'T care about to see what happens it seems to generate thousands of lines of information about the ALSA settings, modules, hardware, mixer settings etc. Hence a lot of space to scroll I guess.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Step 3 is downloading a random script off the Internet. Nope, I'm out.<br></blockquote><div><br></div><div>Tested on scrap box doesn't seem to do any harm but impossible to tell.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
I guess the question is: hardware or software?<br>
<br>
When there is no sound coming out, does anything show sound still being generated? e.g. monitoring volume levels?<br></blockquote><div><br></div><div> Box is now 10,000 miles away last time I saw it you could see the changing volume levels of both the speakers and the microphone.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
If they're bouncing around, I would suspect a hardware problem. With it being a laptop, it could be a wire or something has worked loose and then intermittently breaks connection. e.g. as the laptop warms up or gets flexed.<br>
And in that scenario, I think it would be between the speakers and the sound unit/MoBo jack.<br></blockquote><div><br></div><div>Don't think so as you always get the tones when it boots, makes no difference if you boot it from cold or reboot it through out the day when it is hot you still get the tones but intermittent sound when logged in.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Oh, with it being a laptop; is it incorrectly switching to headphones? Next time it fails, plug a pair in and see if you hear anything.<br>
That could mean an accidental key-combo or a speaker fault as described above.<br></blockquote><div><br></div><div>Only the electrical crackle as contact is made or broken<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Does the loss of sound seem to correlate with a particular action (e.g. application start-up, system event)<br></blockquote><div><br></div><div>Tones on start up, log in maybe you have sound maybe you don't.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Have you checked the log files for any error messages or other info? Is PA reporting "FATAL: Where the heck did '/dev/audio0' go???"<br></blockquote><div><br></div><div>Which logs files to look for?<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
In the past (circa Ubuntu 10/12) Pulseaudio/Gnome would get into a punch-up and the only way I could resolve it was via "pavucontrol".<br>
Although those issues were permanent rather than intermittent.<br></blockquote><div><br></div><div>Might be worth looking at.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
<br>
The other article (<a href="https://help.ubuntu.com/community/SoundTroubleshooting" rel="noreferrer" target="_blank">https://help.ubuntu.com/<wbr>community/SoundTroubleshooting</a><wbr>) contains some steps that might help isolate the issue (esp. when sound appears to have failed)<br></blockquote><div><br></div><div>Ok will read that in detail. It also shows downloading downloading files from the same address as the script we were concerned about in step 3 above. ie <br><pre><a href="http://www.alsa-project.org/">http://www.alsa-project.org/</a> so maybe it is safe.<br><br></pre><pre>All the best<br></pre><pre>Stripes.<br><br></pre> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
