Description

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:

2010-06-13 14:03:16.312 TV: Attempting to change from None to WatchingPreRecorded

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 time (s) 0.01 -> 2
               controls [ 20 0 0.8  ]
              }
          }
     ]
  }
