It's, unfortunately, the only issue :/

Err.. I mean have *both* cards in jack.  I have a ~/.asoundrc with
"platinum51" and "via" devices defined.  I normally do "jackd -d alsa -d
platinum51".  Doing "jackd -d alsa -d platinum51 -d via" makes it only
use the via card.  How can I tell it to use both?

There is some info on how to set up your .asoundrc for this operation in 
the alsa wiki.

Questions regarding SB live card (EMU10K1)

[Vikram Bartakke]

Hello List,


In EMU10k1, Can anyone please tell me how to do ping pong streaming for
audiodata for playback without DMA (ie. CPU controlled). I am also
confused between wavetable cache memory and onboard mapped memory.

What role does the cache as opposed to the sound memory play?

I would be really grateful if I could get to know some information about
this.

Thanks in advance,

Regards,

All audio playback and recording involves DMA. The SBLive, basically, has 
no onboard memory to store audio smaples.

The names you used don't help much, but... All audio samples are in host
memory, the SBLive uses DMA to access them. The "memory" on the card 
itself consists of:

1. 32x32 bits (or close to this, I don't remember exactly) buffer per 
voice, which is used only in playback and to optimize DMA transfers.

2. 2048x32bits DSP memory. This is where the DSP microcode is stored.

3. All other configuration registers.

and that's it.

I want to capture the line-in, but not hear it.  Surely somebody must
have an idea as to how this can be done?

Hi,

I don't have the livedrive but to do what you want with the line in on the 
back of the pci card, I do the following.

Load up alsamixer and find the item Line and press space to capture it. Now go 
to the capture item and press space to capture that aswell, you should now 
here the input from the line in. Make sure that the AC97 Capture volume is at 
maximum. Finally reduce the AC97 volume to zero, you should now not be able 
to hear the input from the line in.

I don't know if this is of any help at all, but maybe if you can replace the 
capture of the Line item with the equivalent on the livedrive (whatever that 
might be) it might work.

Bye,

Gareth.

It should work.  It doesn't.
