Audigy LS SPDIF output.

Audigy LS SPDIF output.

[James Courtier-Dutton]

Hi,

I cannot test SPDIF output because I cannot find a suitable 4 pole mini 
jack that has 3 phone plugs on the end of it, so that I can test spdif out.

I have tried a few different cables, but none of them even work with the 
4front drivers. Once I have a cable that works with the 4Front drivers, 
I will then look into getting the ALSA driver working.

Can anybody help me here?

James

There are two solutions I can offer (assuming when you mention phone 
plugs, that you mean 3-pole 3.5mm plugs):
1) Creative UK offers a set of cables that will take the 3 output lines 
(two of which are 4-pole lines) and convert them into 4 3-pole lines 
(aka stereo lines). These cables are meant for hooking the Audigy 2 up 
to a set of creative labs 7.1 speakers. The website to order the cable 
is: http://uk.europe.creative.com/estore/product.asp?prod=598   . I'm 
not sure why they don't offer this cable in the US, but I assume you can 
order if from the UK.
2) You can make a custom cable (this is what I spent my day doing 
today). You can buy a camcorder cable which has a 4-pole 3.5mm plug on 
one end, and 3 mono RCA type plugs. If you then buy some mono-phone 
plugs (either 3.5mm (aka 1/8") or 1/4" will do), you can cut off the RCA 
plugs and do a little wire splicing/soldering to attach the plugs you 
want. This solution works very nicely (although it takes a little time).

Good luck,

I have a camcorder cable, that has one 4-pole mini-jack connected to 3 
mono RCA plugs, but the connections are all wrong. i.e. the ground or 
sheild on the RCA plugs is not connected to the Ground pole of the mini 
jack as far as the Audigy LS sound card is concerned. It is only correct 
for use with a camcorder.

This is all quite annoying, because a simple mono jack to RCA plug does 
perfectly for SPDIF out to Coax input on the Audigy 2. But this does not 
work with the Audigy LS.

So, I will probably have to go with option (1).

I went and put the Audigy LS in a Windows 2000 machine, and found that 
putting a simple mono mini-jack (2 pole) -> RCA did SPDIF out from the 
Audigy LS to my external decoder, just the same as from an Audigy2. I 
only tested PCM Stereo out from the SPDIF in windows, because I don't 
have any windows program that will output AC3 to SPDIF.

After some trial and error, I now have enough info to implement SPDIF 
out from the Audigy LS in ALSA.

Reg: 0x42 holds the AES bits.
Reg: 0x45 = 0 for SPDIF out,  0xf00 for Analogue out.

PCM output works, but AC3 does not yet. There must be some resamplers or 
extra mixing in the way.

I will submit a patch soon for PCM stereo over SPDIF.
I will have to do more tests to get AC3 working.

Cheers
James

[PATCH] Audigy LS SPDIF output.

[James Courtier-Dutton]

I have uploaded new versions of:
audigyls.c
AudigyLS.conf

http://www.superbug.demon.co.uk/alsa

New feature:
1) SPDIF output of PCM stereo sound.

Bugs:
Output of AC3/DTS does not work yet even though setting of non-audio 
bits is currently working. The card must be doing some resampling, or 
mixing of some other inputs.

Cheers
James

This new patch, implements full SPDIF Stereo PCM and also AC3/DTS output.
These new versions implement AC3/DTS output where the others did not.

One can use a standard stereo mini-jack cable to two RCA plugs cable.
Full explanation in the audigyls.c source code, as comments.

See attachements.

James
