I agree with Paul. This is a problem with PA, alsa works as expected and
perfectly OK with the envy24-chipset.
Even if one likes to call it a "bug" that alsa presents all envy24-cards
more or less the same though they are physically quiet different, I
would call this a minor flaw since technically there is nothing broken here.
Reading the thread on the PA-site I feel a bit uneasy. Lennart demands
alsa to report a "front"-device wich is nonsense since AFAIK only the
terratec 5.1 uses the envy24-chipset to produce a set of outputs for
surround-speakers. All others are cards for musicians delivering 2+2,
4+2 ore more analogue/digital i/o ports that are all considered the
same, delivering a pristine hifi-signal that the user is invited to send
whatever source he/she likes to send to.
What will PA do with a Delta 10x10? Trying to send "front" to the first
2, "rear" to the next 2, a lowpassed "sub" to the fith and then what?
Why cant PA just offer a stereo-out for the first 2 ports of the envy
and secondary stereo-outs for the rest plus a digital-out for the
spdif-ports on these cards? Do they consider users, that spend quite
some money on such a card, too stupid to find out, why the secondary
stereo-outs do not deliver a signal with a MAudio audiophile?
And NO! I would NOT consider it a progress, if alsa would start to tell
me, that the first two ports of my MAudio would be "front-speaker-outs"
for they are not.
This musing about "broken" alsa-drivers that need to be "fixed" in
the
thread at PA increases the bad feeling about PA's relation and awarenes
to pro-audio.

Now that would be shocking I'd say. Since Suse 8.0 the ICE1712
was
always the most reliable chipset one could possibly find for
Linux. So
that would be a major regression and should be a show-stopper
for alsa.
BUT: the link points to a bug that affects puls audio and it
affects it
with a EWS88MT wich is one of the not-so typical ICE1712-cards
like the
EWX or the MAudio Audiophile and Delta-Series.
So how about these cards and alsa/jack? Any trouble out there
with
bleeding-edge distros?
my reading of this (and the related ALSA bug report) is that this is a
Pulse-only bug, because its related to Pulse's attempt to provide a
mapping of whatever-it-is-that-the-hw-provides into
standard-things-that-users-can-know-and-love.
JACK will just use the channels as single, undifferentiated channels
and doesn't care about their names, function,etc. etc.
i could be wrong in my assessment.
I think you are correct. Pulse points to alsa as the culprit, alsa
ignores the issue, it may _not_ be an issue for alsa, I don't know. -----BEGIN PGP SIGNATURE-----
