Now I'm trying to resuscitate the old set. Got 'em plugged into my ubuntu web server pc and got 'em working again. Sort of. One speaker had broke loose of it's little enclosure, so I opened it and screwed it back in place. However it doesn't work, no sound out (other speaker and the woofer do work). When I plug headphones into the pc I get stereo.<br /><br /> Oddly, when I crank down the volume of the 'dead' speaker, I seem to get decent mono sound out of the remaining two (instead of just one track louder). Why would that be?<br /><br /> Anyway, any tips on diagnosing/repairing a dead speaker? The leads appear to be intact. Could I replace it with a 'generic' bare speaker of similar size? (I actually had one that would have been a perfect replacement which I tossed about a year ago :-@)<div class="edit_text">EDITED: 8 May 2016 14:56 by DSMITHHFX</div> </div> <div class="message_footer"> <div class="message_footer_links"><a href="lpost.php?webtag=DEFAULT&reply_to=41742.1&return_msg=41742.1" class="reply"><span class="image post"></span>Reply</a></div> <div class="message_vote_form" data-msg="41742.1"> <span class="rating">0/0</span> <span class="image vote vote_down vote_down_off" title="Vote Down"></span> <span class="image vote vote_up vote_up_off" title="Vote Up"></span> </div> </div> </div><a name="a41742_2"></a><div class="message" id="message_41742_2"> <div class="message_header"> <div class="message_from"> From: CHYRON (DSMITHHFX)<span class="message_time"> 8 May 2016 16:33</span> <div class="clearer"></div> </div><div class="message_to">To: ALL<span class="message_count">2 of 7</span><div class="clearer"></div> </div> </div> <div class="message_links"> <a href="lmessages.php?webtag=DEFAULT&msg=41742.2">41742.2</a></div> <div class="message_body"> After some googling it appears there may be an Ubuntu audio config issue with 2.1 setup (the pulse volume/mixer doesn't even have a 2.1 option, it goes from plain stereo to 4.1).
