Yes, all four are doing it wrong, along with the many more who haven't posted and all those who gave up with Linux because the sound doesn't work properly. Fucktards every one. Linux doesn't need people like that.
Really? I haven't had a sound driver problem in over 10 years on Linux.
The people who keep waving this non-issue around should be providing some backing information, cos it sounds like they are making up complaints about something that was solved a long time ago.
