this is likely because the newer version of cmipci driver supports
24bit SPDIF output, but no input yet...
a reminder that for some time now, JACK supports the -P option which
limits it to playback only. useful if that's all you want and/or all
your hardware can do.
--p
Actually it is playback (and thus duplex) that I'm having trouble with
(alsa-driver-0.9.8 and jackd-0.80.0). Capture works fine from hw:0,2 using jack via
my .asoundrc. It's when I try and tell jack to play (both -P and -D options) to
hw:0,2 that my ad/da converter gets blasted into this weird loop (a midiman flying
cow), like I described in my earlier post. If the whole thing is caused by the
discrepancy in the bit sizes in newer versions of alsa-driver, i'm fine using 0.9.2
until that's resolved (i'm very happy to test when it is, btw), since that version
works perfectly for full duplex spdif operation. For posterity I posted a bug to
alsa's sourceforge site:
http://sourceforge.net/tracker/index.php?func=detailatid=390601aid=834652group_id=27464
the problem is that if you use 24bit on playback, the capture may not
work as full duplex. IIRC, unfortunately, there is no option to limit
the format for hw type. instead, you can try the plug layer with the
format parameter, such as
pcm.cmi {
type plug
slave {
pcm hw:0,2
format S16_LE
}
}
note that the above is untested :)
Paul, is there any option to specify (limit) the format in jackd?

Re: [Alsa-devel] alsa-driver-0.9.8, jack, cmipci
Hello again. Further research:
I tried an earlier version of jack (0.71.0) with alsa-driver-0.9.8, accessing hw:0,2
via my .asoundrc. I get the same result as before, but in addition this particular
version of jackd tells me:
...
Sorry. The PCM device cmipcidoesn't support the same sample format for capture and
playback.We cannot use this PCM device.
...
and jackd quits.
Accesssing hw:0 works fine with jack, but again, I can't record from spdif. So there
really seems to be a problem with hw:0,2 in alsa-driver-0.9.8 (I also test 0.9.7c,
same results).
Does anyone have any thoughts? If this really is not a problem with alsa I'll post to
the jack list instead, and use 0.9.2 in the meanwhile. Please let me know.
Thanks!

Hi,
Alsa-driver-0.9.8 doesn't work properly for full duplex operation with jack-0.
80 and spdif from a cmedia 8738. (I had been using alsa 0.9.2, before, and it
worked just fine). Here's what happens:
starting jack with
jackd -d alsa -d cmipci
causes the D/A Valid light on my external DA converter (a midiman flying cow)
to go off, the levels to get pegged, and i can hear what sounds like spdif in
my speakers. I quit jack, the flying cow remains in it's weird loop, and i do
something like starting and quitting esd to reset it.
if i only do capture (jackd -d alsa -d cmipci -C) it seems fine, but of course
no output.
if i don't use .asoundrc (jackd -d alsa -d hw:0) the output is fine, but jack
can't read any input. Note: recording without jack using arecord doesn't work
with hw:0,0, but arecord -Dhw:0,2 does (as expected)
Since 0.92 works with the same jack version (0.80), I decided to post here fir
st. I'm more than willing to send along any other info to help resolve this p
roblem.
