This seems to have fixed AC3 Passthru mode on SB Live (rev 7) cards.
Just so you know, all SB Live cards worked before for AC3 Passthru
except the rev 7 cards.
I just got a report on the xine-user list about it.
Ok, so you did not know you were fixing it, but well done anyway ;-)
err, frankly speaking, i still don't figure out why with this change
the pass-through works. i'm glad to to hear a good news, anyway ;)
Just wanted to let you know that it wasn't the changes in emu10k1_main.c,
but the changes in emumixer.c that made my (I was the one reporting it on
the xine ML) rev07 card working.
The joke is, that this behaviour is caused by a mistake. Here is the right
patch against current CVS:

At least, we know that for rev07 cards we shouldn't modify GPOUT0. These
cards have separated the digital output or shared with an analog output?

I would appreciate having more functionality in alsamixer because it is currently the only graphical mixer that fully supports most of the supported hardware.

Hi Takashi! * Takashi Iwai writes: Markus, could you try the latest cvs version, which fixes the real behavior, whether digital out works? if it doesn't work again, then definitely GPOUT0 is the spot.

Takashi My SB Live (non 5.1) does not have a Digital/Analog Jack, it just has a Digital Jack, so I would prefer that the Digital/Analogue Switch in alsamixer was removed for rev06 cards and below, but present for rev7 cards and above. Currently, toggling the alsamixer Digital/Analogue Switch has no effect what so ever. I think this rev07 passthru issue might have been the user just not knowing about the Digital/Analogue switch in alsamixer.

Re: [Alsa-devel] Requesting guidance
hi, as i looked trough the code of my ens1371 driver, a few weeks ago, i recognized that it would be possible to have a real 4-speaker enviroment. as the ens1371 have 2 DAC's its not difficult to make this happen, and i know that it works with win$. it works that way that the line-out will be switched as a second line-out. the ens1370-driver has such kind of switch, probably you have to buy a soundcard with a ens1370 chip. i would implement such kind of switch to the ens1371-driver too, but dont know which bit has to be set. i didn't asked creative till now, cause i think they want that i subscribe a non-disclosure-agreement, and this wont help to our project. maybe it could be found out with some kind of reingeneering. but anyway, for your project i think you didnt have to do much coding for routing 4 mono-channels to 4 physical channels, it could be solved with the runtime-configuring-options of alsa, the only thing your app has to do then, to write to the right 'logical' PCM's. this could be done with every multi-channel soundcard. joy On Mon, 15 Apr 2002, cjs 2895 wrote: Howdy folks, I've got an idea for a game I'd like to build for my kids. To make it work like I want I need to have four mono sound channels feeding into four physical speakers. To make that work it looks like my options are: 1) Use four separate sound cards (PCI or USB) 2) Do some coding to use each channel in a sound card to drive a separate speaker. I like option two the best because its cost effective, and I think the newer Sound Blaster cards will drive four speakers (even if not, two cards is better then four). Unfortunately I don't think Linux's OSS can handle either of these options so now I'm looking to Alsa as a solution. From reading the Alsa manual it looks like I can do what I want by interleaving the sound buffers in one memory space. Is that the best approach? Its been a week since I read the manual, so I don't recall if I can do something like a select() loop to feed data to the sound cards as needed, but I'm thinking that would be easier if the method is available. Can anyone give me some guidance on how to proceed? I would appreciate it. Also, I haven't bought any sound cards yet, so if there is another make that might be better suited for this application (and is also cheap) please clue me in.

I have been knowing about it all the time. And as I wrote to Takashi this had/has nothing to do with my problem. The switch worked, but AC3 wasn't passed through, so this is surely not the readon. I wouldn't have gotten any sound then, or better only digital enabled sound, because the preset is digital sound 'ON'. Regards Markus Plail Sorry, it was only an idle thought.
