Can anyone point to a 12.3-friendly way to get a compressor and equalizer going? A limiter if such exists would be great too.
You can use a Ladspa plugin:

For a graphically equalizer, you can use this:

which in turn uses Ladspa.
Hmm. I installed the ladspa package via zypper, once I figured out that it contains a good many of the plugins I might want, then as per your url above, created the following ~/.asoundrc: pcm.ladcomp { type plug slave.pcm "ladcomp_compressor"; } pcm.ladcomp_compressor { type ladspa slave.pcm "ladcomp_limiter"; path "/usr/lib64/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/lib64/ladspa"; plugins [{ label fastLookaheadLimiter input { #InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release time (s) 0.01 -> 2 controls [ 20 0 0.8 ] } }] } And did `sudo service alsasound restart`. Made no change whatsoever in alsamixer. I expected to see more controls available to me (no love if I ran it as root either). Suggestions, clues for the clue-impaired? Thanks.
