Hello, I can confirm, that this patch is working fine with 6 Speakers. Mute-/unmute and volume control of all 6 channels are working fine. I used a Soundblaster X-Fi Titanium (EMU20k2) Best regards, Frank Roth _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
