PATCH 1/1 Fixes AC3 output on Audigy2 sound cards.

Hi,

This patch adds a DSP patch to fix an spdif_bug on some Audigy2 cards.
It also does detailed identification of the capabilities of the sound card so that the patch is only applied to the sound cards that really need it.

Signed off: James Courtier-Dutton

The Audigy2.conf file must be placed in alsa-lib. /usr/share/alsa/cards. audigy-ac3-fix.diff.txt is a patch against the current CVS.

Hi,

This patch adds a DSP patch to fix an spdif_bug on some Audigy2 cards. It also does detailed identification of the capabilities of the sound card so that the patch is only applied to the sound cards that really need it.

Signed off: James Courtier-Dutton

The patch seems to have both this change and the addition of capabilities selection. Could you split into two patches?

thanks,

Takashi

1.0.9rc2 needs the changed Audigy2.conf file, otherwise AC3 passthru will not work. The DSP code in alsa-driver changed to fix a hardware bug in some Creative sound cards,

Did you also apply the patch to the Audigy2.conf file, that goes with this patch? The spdif out routing has changed.

when did this changed in the driver btw?

1.0.9rc2 needs the changed Audigy2.conf file, otherwise AC3 passthru will not work. The DSP code in alsa-driver changed to fix a hardware bug in some Creative sound cards,

i guess that this's this commit:

2005-03-22 21:58 tiwai

* pci/emu10k1/emufx.c: Summary: Fixes AC3 output on Audigy2 sound cards

This patch adds a DSP patch to fix an spdif_bug on some Audigy2 cards.

is'nt it?
