I think, there is only one more control "Headphone". > For example: EXTOUT_IEC958=1 -> AC3 Passthru is working after ld10k1 > startup+init_audigy? > > What did you mean with swapped channels? How can i influence this with > original driver? I think Audigy 2 (maybe some audigy 1 too) has hw bug, and for spdif output channels needs to be swapped (left <-> right). if you look in emu10k1_main.c there is definition for your card {.vendor = 0x1102, .device = 0x0004, .subsystem = 0x00521102, .driver = "Audigy", .name = "Audigy 1 ES [SB0160]", .id = "Audigy", .emu10k2_chip = 1, .ca0102_chip = 1, .spdif_bug = 1, .ac97_chip = 1} , try remove line with .spdif_bug = 1, > > > Next i have some problem to understand the mixer controls. > > > At first there is no Mute-Control for: (independent of ld10k1 > > > loaded or not) Master, PCM, PCM-*, Front, Surround, ... > > > This is a real pity. > > > > For mute control you can look in > > https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2137 > > there is patch, it is old, but probably will work.

Upmixing means the internal 5.1 prologic decoder? Is there any way > to use it with alsa devices? It means simple copy front to other channels (no prologic). I think there is prologic alsa-lib plugin, but I am not sure. Peter Zubaj ------------------------------------------------------------------------- Using Tomcat but need to do more?
