Hi,
I'm not sure if this is 100% the same issue, but my problems started
again when Debian upgraded from pulseaudio 8 to 9 recently.
Even though I still use tsched=0, I hear huge amounts of clicks and pops
while playing back (everything sounds like a very old vinyl recording
now...). Enabling tsc

It worked with previous versions. And even if it doesn't work - what is
the recommended step here? Remove pulseaudio?
Thanks & best regards

Ok. So the "high channel count" part is fixed with 6.0.
The "non interleaved access" was never a problem (emulated by alsa plug
layer).
Tsched=0 workarounds...should in general be fixed in ALSA rather than
PulseAudio. Raymond's patch is probably correct but I'm not qualified to
review it. Raymond
tsched=0 !!!
That seems to do the trick! Pulseaudio 6.0 is running with every app
simultaneously without a glitch! I will do more testing, but it looks perfect
right now!
Thank you all!

Thanks, so in fact the card is detected now.
The crackling looks like a driver problem but I'm not sure. You could
try to change this line in default.pa:

to this:

Hi,
I built PA 6 from git and got the exact same verbose output of aplay and
arecord than I posted on 2014-10-27.
The apps are working though - partly. Browsers and music apps like
aqualung play sounds now, but there are a lot of dropouts in the sound.
Sometimes, it even plays back at the wrong s

PulseAudio 6.0 has now been released and it includes the multichannel
fallback, which should have solved your issue, but apparently it has
not.
Could you submit a new PulseAudio verbose log with PA 6.0? Thanks.

Peter, forget the last comment. I read your patch again and it looks
good, so I've pushed it now.
(This does not change the fact that we still need a new verbose log from
