From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.19-7.0.1 i686) The emu10k sound driver contained in the latest upgrade kernel doesn't allow to tailor bass or treble levels anymore; this results in REALLY poor quality of the generated sound. Some further investigation reveals that all related code is wrapped in #ifdef TONE_CONTROL ... #endif in drivers/sound/emu10k/{main,mixer.c}, without any location where this is actually enabled/defined. I rebuilt the emu10k.o module using a patch, which you can find at <http://www.cygnus.com/~manfredh/rhl7.0/linux-2.2.19-emu10k-tone_control.patch> and which fixed the problem for me on my SoundBlaster Live! Player 1024. FWIW, this seems to be related with an entry for 2.4 kernels of RHL 7.1; see <http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=32723> Reproducible: Always Steps to Reproduce: 1.Boot system with 2.2.19-7.0.1 kernel and a sound card with an EMU10K chip included 2.Start sound mixer application 3.Look for any controls for bass or treble Actual Results: There are no controls available. Expected Results: Two sliders (one for bass and one for treble) are available with 2.2.17-14 (and with my patch applied on 2.2.19 as well;-) )
This report can be closed, as current versions in RHL 7.2 and 7.3 can utilize the emu10k1 driver and tools from <http://sourceforge.net/projects/emu10k1> to enable treble/bass controls.
Thanks for the note!
