Hello,
I'm new on this mailing-list. I tried asking this question on
general-purpose forums, but I realise this is too specific. I hope this
place is better suited.
I have my own server. And I thought it would be nice to have this server
hooked up to the HiFi, and thus enable any PC on the LAN to send sound
to the HiFi!
Setup was not straightforward, none the least because Mandriva's paprefs
seems to be partly broken, and there's ZERO documentation on Pulseaudio
networking on Mandriva. Still, I managed; all in all, it's just a matter of:
— adding
load-module module-native-protocol-tcp
load-module module-zeroconf-publish
to /etc/pulse/default.pa on the (Debian) server,
— adding
load-module module-zeroconf-discover
to /etc/pulse/default.pa on the (Mandriva) client,
— managing authentication, either through ACL or with cookies.
Alternately, the whole zeroconf parts can be replaced by a single line
on the client side (I got this line thanks to paman; it was probably
generated by zeroconf-discover in the first place):
load-module module-tunnel-sink server=[my_server_IP]:4713
sink=alsa_output.hw_0 format=s16le channels=2 rate=44100
sink_name=tunnel.sphinx.local.alsa_output.hw_0
channel_map=front-left,front-right
Anyway, I still have two problems, which are probably related:
*1/ Very chopped sound, and freezed video, when using the tunnelled sink*
When I play a wav file with VLC, I only get an occasional bit of sound
once in a while, even though VLC's slider seems to run fine.
Curiously, when I play the same wav file with mplayer, the sound gets
perfectly to the speakers. However, mplayer itself seems to be lost. It
displays a line about like this:
A: 0.1 (00.1) of1.0 (00:01.0) 0.1%
with no apparent trend up in the numbers and a regular flash of
“unknown” (if I saw correctly) between the first pair of brackets.
As for video, still with mplayer, it takes ages to actually start, and
then, I have sound but no video, and mplayer is extremely slow to
respond to key strokes.
I must add that networking itself is not at fault. If, instead of
relying on the tunnelled sink, I change of server with
PULSE_SERVER=my_server mplayer ~/my_wav_file.wav
then it is as good as with a local sink (which is not perfect, see below)…
So it is obviously a tunnel-specific problem. Unfortunately, changing of
PA server is not an option for me, because Mandriva's pavucontrol
(pulseaudio 0.9.21) seems unable to connect to Debian's daemon
(pulseaudio 0.9.10): I get an error about pa_context_get_card_info_list
being “Not supported”.
*2/ Spurious pauses in video playback when using local sinks*
Now with local playback. As soon as a remote sink is available, be it
through zeroconf, or directly with the tunnel-sink module, then /local/
video playback on /local/ sinks with any player (VLC, mplayer, xine)
plays fine, EXCEPT (that's a big except…) every 5 minutes or so, there's
a more-or-less-15-second pause in playback!
So for now, I'm back to square one, with both “module-zeroconf-discover”
and “module-tunnel-sink” disabled on the client side (no Pulseaudio
network)…
Is there a Pulseaudio veteran here that would have advice, tips, or
anything to help me?
Thanks,
Hello,
Although the problem is still there, the weirdest part of it is gone :)
My client's syslog was spammed by klogd with the following text without end:
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata3.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0
cdb 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
res 51/20:03:00:00:00/00:00:00:00:00/a0 Emask 0x1 (device
error)
ata3.00: status: { DRDY ERR }
Following an Internet advice, I ran this:
hal-disable-polling --device /dev/sr0
I guess some sort of “bus fill” was happening… Anyway, the log's quiet
now. And more importantly, local playback is now perfect (tested with
mplayer). Problem #2 above is gone. That leaves problem #1.
Good news is, as previously, running mplayer like this:
PULSE_SERVER=my_server_IP mplayer movie.avi
gives the same result as local playback, which is, this time, perfect!
(at the cost of 25 to 50% CPU just for PA on the server, and 10°C more)
But with this setup, I cannot adjust sound in the local (client)
pavucontrol…
Bad news is, as previously, running mplayer on the tunneled sink
(appears locally, so I can adjust levels) lets me hear audio, but I have
no picture, and mplayer console display is kind of freezed.
Is there additional information that would help you help me?
