Description Peter Sampson 2015-12-16 10:12:42 UTC

Tested on audacity-win-r13f1349-2.1.2-alpha- but occurs in 2.1.1 too so not a regression.

Also occurs if you:
1) use Audacity default Prefs
2) disable SC4
3) close Audacity
4) restart Audacity - SC4 is now enabled and available again

Comment 1 Gale Andrews 2015-12-16 16:08:47 UTC

SC4 is disabled OK on Mac and Linux.

Comment 2 Peter Sampson 2018-02-13 06:54:31 UTC

Tested on W10 with 2.2.2 RC1

this still occurs so changed flag to Windows (all)


But it's high time we were removing SC4 anyway ...

Comment 3 Peter Sampson 2019-05-11 11:38:34 UTC

Testing on W10 with 2,3,2 RC001

SC$ is still not properly disabled - on restart of Audacity it appears again as enabled.

We no longer have a "Stereo to Mono" effect so that part of the bug no longer applies.



I repeat my comment from 15 months ago in Comment #2

Comment 4 Peter Sampson 2019-08-13 11:23:55 UTC

We no longer ship SC4 now so this is an upgraders issue only - but it works properly on W10 with audacity-2.3.3-alpha-317-44c46f7574e89638823c6cc895caa2cd5135d427


On relauching Audaqcity at Step 6 the Plug-in Manager shows tha SC4 is properly in the Disabled section and is not re-enabled
