 Hello,

 After recently upgrading to mythbuntu 10.04, I noticed that some files
 have no sound while other behave as expected (i.e. the sound is nicely
 leveled / normalized).

 I have been using the .asoundrc ladspa plugin solution for volume leveling
 (like in the first post here: [http://www.gossamer-
 threads.com/lists/mythtv/mythtvnz/422662] ) for about 1 year and never
 noticed this type of problem with the sound.

 When I look at the frontend logfile it shows:

 {{{

 ALSA parameters

 }}}

 Also, another different video (this time in mythvideo) shows the same
 problem:


 {{{

 My .asoundrc is:


 {{{
  pcm.ladcomp {
       type plug
       slave.pcm "ladcomp_compressor";
   }
  pcm.ladcomp_compressor {
       type ladspa
       slave.pcm "ladcomp_limiter";
       path "/usr/lib/ladspa";
       plugins [
           {
               label dysonCompress
               input {
                   #peak limit, release time, fast ratio, ratio
                   controls [0 1 0.5 0.99]
               }
           }
       ]
   }
  pcm.ladcomp_limiter {
       type ladspa
       slave.pcm "plughw:0,0";
       path "/usr/lib/ladspa";
       plugins [
           {
               label fastLookaheadLimiter
               input {
                #InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release

                controls [ 20 0 0.8  ]
               }
           }
      ]
   }

 }}}
