Try running pulseaudio with debug logging. Perhaps it would tell you
more.

Hi Victor :



First i launch Pulseaudio :

bash-3.00# /usr/local/bin/64/pulseaudio/pulseaudio --log-level=debug
W: This program is not intended to be run as root (unless --system is
specified).
I: device opened in O_RDWR mode.
I: created 0 "solaris_input" with sample spec "s16be 2ch 44100Hz"
I: created 0 "solaris_output" with sample spec "s16be 2ch 44100Hz"
I: created 1 "solaris_output.monitor" with sample spec "s16be 2ch 44100Hz"
I: Loaded "module-solaris" (index: #0; argument: "device=/dev/audio").
I: loaded 1 modules.
I: Loaded "module-detect" (index: #1; argument: "").
I: Loaded "module-esound-protocol-unix" (index: #2; argument: "").
I: loading cookie from disk.
I: Loaded "module-native-protocol-unix" (index: #3; argument: "").
I: starting with empty ruleset.
I: Loaded "module-volume-restore" (index: #4; argument: "").
I: Loaded "module-rescue-streams" (index: #5; argument: "").
I: Loaded "module-gconf" (index: #6; argument: "").
I: Daemon startup complete.
I: Unloading "module-detect" (index: #1).
I: Unloaded "module-detect" (index: #1).


Now the Pulseaudio server is initialized, i launch on my Csound console :

bash-3.00# ./csound -+rtaudio=pulse -o dac examples/xanadu.csd

Here the Pulseaudio output :

I: created 0 "Native client (UNIX socket client)"
I: client 0 changed name from "Native client (UNIX socket client)" to
"csound"
I: created 0 "csound-out" on solaris_output with sample spec float32le 2ch
44100Hz
D: Memory block too large for pool: 1048576 > 16368
D: memblockq requested: maxlength=264600, tlength=176400, base=8,
prebuf=174636, minreq=1764
D: memblockq sanitized: maxlength=264600, tlength=176400, base=8,
prebuf=174640, minreq=1760
I: Creating new entry for 


As the render hangs up, i kill manually the process but not the Pulsaudio
server, which says :

I: freed 0 "csound-out"
I: freed 0 "csound"


So i'm able to launch in another console :

bash-3.00# /usr/local/bin/64/pulseaudio/paplay
/export/home/root/Csound5.09.0.cc.64/Xanadu.wav (Xanadu.wav obtained before
the actual tries and spared)

I: created 1 "Native client (UNIX socket client)"
I: client 1 changed name from "Native client (UNIX socket client)" to
"paplay"
I: created 1 "/export/home/root/Csound5.09.0.cc.64/Xanadu.wav" on
solaris_output with sample spec s16be 2ch 44100Hz
D: Memory block too large for pool: 1048576 > 16368
D: memblockq requested: maxlength=132300, tlength=88200, base=4,
prebuf=87318, minreq=882
D: memblockq sanitized: maxlength=132300, tlength=88200, base=4,
prebuf=87320, minreq=880
I: Creating new entry for 
D: Memory block too large for pool: 65536 > 16368
D: Memory block too large for pool: 22664 > 16368
D: Memory block too large for pool: 16384 > 16368
I: freed 1 "/export/home/root/Csound5.09.0.cc.64/Xanadu.wav"
I: freed 1 "paplay"


I heard as well Xanadu.wav, now it's released and i'm able to launch another
.wav file i have, called "lindau.wav" ; the server gives :

I: created 2 "Native client (UNIX socket client)"
I: client 2 changed name from "Native client (UNIX socket client)" to
"paplay"
I: Restoring volume for 
I: Restoring sink for 
I: created 2 "/export/home/user/scwk/scmu/lindau.wav" on solaris_output with
sample spec s16be 2ch 44100Hz
D: Memory block too large for pool: 1048576 > 16368
D: memblockq requested: maxlength=132300, tlength=88200, base=4,
prebuf=87318, minreq=882
D: memblockq sanitized: maxlength=132300, tlength=88200, base=4,
prebuf=87320, minreq=880
D: Memory block too large for pool: 65536 > 16368
D: Memory block too large for pool: 22664 > 16368
D: Memory block too large for pool: 16384 > 16368
I: freed 2 "/export/home/user/scwk/scmu/lindau.wav"
I: freed 2 "paplay"

Played and released as well.


>From that all we can deduce that the complains about too large blocks aren't
worrying, i mean either for the playback nor also for the realtime render,
right ?


Cheers,

Sergio

I get many more messages under loglevel debug. I'll copy them to you
as soon as I have the chance.
