--MP_/CyCn1yh1=Fmzym9gzAvLO+T Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Disposition: inline Hi! While trying to setup multichannel output using SB Audigy (CA100), PulseAudio and snd_emu10kx I came into problem with sub/center outputs being mute. After some digging, I've found that the driver code enabling them is disabled and enabling it (see attachment) solves my issue. Another problem is that I'm using analog outputs and until I set dev.emu10kx.0._digital=0 sysctl, analog/digital output produces only digital noise. Hearing that noise every time you turn on your PC, after the module loads and before sysctl runs can by quite annoying. I think both these issues were mentioned earlier on this list but didn't get enough attention. This being said, huge thanks to Yuriy for making this possible! -- xmpp:pocketer@jabber.gda.pl --MP_/CyCn1yh1=Fmzym9gzAvLO+T Content-Type: text/x-patch; name=emu10kx.diff Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=emu10kx.diff --- sys/dev/sound/pci/emu10kx.c.orig 2008-09-18 20:13:11.000000000 +0200 +++ sys/dev/sound/pci/emu10kx.c 2008-09-18 20:49:31.000000000 +0200 @@ -2036,22 +2036,22 @@ /* fx4 (pcm2) to center */ EFX_CACHE(C_CENTER); EFX_ROUTE(NULL, FX(4), M_FX4_CENTER, C_CENTER, 100); EFX_OUTPUT(NULL, C_CENTER, M_MASTER_CENTER, A_OUT_D_CENTER, 100); -#if 0 +#if 1 /* * XXX in digital mode (default) this should be muted * because this output is shared with digital out */ EFX_OUTPUTD(C_CENTER, M_MASTER_CENTER, A_OUT_A_CENTER); #endif /* fx5 (pcm3) to sub */ EFX_CACHE(C_SUB); EFX_ROUTE(NULL, FX(5), M_FX5_SUBWOOFER, C_SUB, 100); EFX_OUTPUT(NULL, C_SUB, M_MASTER_SUBWOOFER, A_OUT_D_SUB, 100); -#if 0 +#if 1 /* * XXX in digital mode (default) this should be muted * because this output is shared with digital out */ EFX_OUTPUTD(C_SUB, M_MASTER_SUBWOOFER, A_OUT_A_SUB); --MP_/CyCn1yh1=Fmzym9gzAvLO+T--
