Greetings:
This question is directed to Lee Revell and anyone who is using or has
tried to use the multichannel capability for the ALSA SBLive module.
When I select multichannel duplex operation in QJackCtl I get 16
channels for input and two channels for output. Is that the default I/O
channel arrangement ?
Regardless of framesize I get constant xruns. SR is set to 48 kHz, and
the period size has been left at 2. Has anyone figured a way to defeat
the dreaded xrun with setup ?
Card is an SBLive Value, system is Demudi 1.3.0rc1, ALSA version is
1.0.10rc1, JACK is 0.100.0.
Best,
dp

You should get 16 in and 16 out. You have to individually select the
multichannel devices for input (hw:x,2) and output (hw:x,3).

It's no different from diagnosing xruns on any other system...

What Lee said.
I am using the EMU10K1 driver on both an Audigy2 EX and ZS models.
These cards both have 6 analog inputs (3 stereo lines) and the EX is 6.1
out (7 analog outputs) and the ZS is 7.1 out (8 analog outputs). I have
worked out the mapping from the pcm_capture and pcm_playback ports to
the physical analog inputs and outputs which I will share if you are
interested.
The only problem I found is that the alsa-mixer volume control sliders
are left-right switched for all of the stereo output pairs. I mean, if
you plug a standard 1/8" stereo-to-RCA cable into the stereo output on
the card, the appropriate left slider controls the signal on the red RCA
plug - which is typically the right channel - and vice versa. This is
true for all stereo output pairs.
I reported this bug to the ALSA bugtracker about a year ago
(https://bugtrack.alsa-project.org/alsa-bug/view.php?id=904), but the
behavior persists....

Does this work on older SBlive 5.1 cards as well?

Cool! Thanks Lee.
I know I've seen stuff about this previous and you have long been a
supporter of the usefulness of SB cards. I guess it's nice to know that
I have about 5 SBlive 5.1 (about $19.00 for the OEM version) laying
around that are multi channel cards of sorts! :)
