                          <br>
                          I'm down to my last couple of minor issues.
                          Thanks for the help so far!<br>
                          <br>
                          I have audio set to alsa:default. Above about
                          1.1x time stretch there is some noticeable
                          skipping/clicking in recorded playback audio.
                          I have not had this issue with mplayer which
                          also uses alsa. Admittedly this is a pretty
                          minor.<br>
                          <br>
                          Ubuntu audio has been fairly well behaved for
                          the last few years, but earlier experience
                          tells me this can be a real can of worms.<br>
                          <br>
                          Log attached.<br>
                          <br>
                          Am I missing something obvious?<span></span><br>
