 |
|
Hi,
I just set PulseAudio on my system : what a surprise, all is working fine  ... except for these two things where I need help :
- Chromium, if it's the first started, bypass PulseAudio and use ALSA directly and so, I can't use Amarok after ... (if I start Amarok first, all is fine and Chromium use PulseAudio via ALSA reconfiguration /etc/asound.conf). Here are error when Chromium is the first playing :
| Code: |

- SMPlayer can't play 5.1 AC3 track (pass-through) to Pulse driver (audio tab) : no sound ; I have to use ALSA driver to play AC3 to my Logitech 5.1 kit (which is working fine, and auto-disable all 2.0 numeric stream before play ...)
- I can't find any PulseAudio profile for 5.1 numeric : there is just many 5.1 analog but no one for numeric (or only for stereo playback ...) ; thus, this problem can be linked the the previous point ...
Here are a list of profiles (sorry, don't know why it's in french ...) :

As you can see, there is only "analog" available for more than 2.0 stream ...

I've found the flash problem ... Just install libflashsupport and now, got PulseAudio support with flash  ... hum, in fact, it's not "true PulseAudio" but "ALSA playback to PulseAudio" (really, I don't know which driver flash was using before that...).

| The second part is wrong - with alsa-plugins[pulse] there should be no need for libflashsupport - at least not with >=flash 10. |

Yes, that's was saying portage ... but before, I was getting problem .. now, it's working ... :

I'm running Gentoo ~amd64 and so, it works for me.
Here is alsa-plugins already installed :
| Code: |
[ebuild R ] media-plugins/alsa-plugins-1.0.24 USE="ffmpeg pulseaudio -debug -jack -libsamplerate -speex" 0 kB
|
I will try to remove libflashsupport and re-emerge alsa-plugins + reboot and check if it's working or not .. come back after that ... :
| Code: |
emerge --unmerge libflashsupport && emerge alsa-plugins && reboot
|
EDIT: you right after reboot, Flash was wokring (ALSA Playback) without causing any issue to other applications ... I don't understand but it's good

UP 
I'm trying to get PulseAudio working on network (from the PC to the SERVER) ... I can see (on my PC) all PulseAudio "remote sinks" with "padevchooser" ... but, when I click on another sink, there is no effect at all ... I'm looking the network traffic, and nothing is sent ... Is it "padevchooser" which won't do the trick ?
I will try by using "pacmd" ...
Here is something I've found ... running on the PC, I can get information about all servers :
| Code: |

EDIT: in fact, by using pacmd, I see only one sink :
| Code: |
loopx@loop ~ $ pacmd list-sinks
Welcome to PulseAudio! Use "help" for usage information.
>>> 1 sink(s) available.
* index: 0
name: <alsa_output.pci-0000_00_1b.0.analog-stereo>
driver: <module-alsa-card.c>

suspend cause:
priority: 9959

balance 0,00
|
which is local to my PC ... and is what I can just use ... that's not a network use 
| Quote: | EDIT2: from here : http://wiki.laptop.org/go/PulseAudio
You can run padevchooser to control the pulseaudio server. This tool will prompt you when a new server on the network has been discovered. You can set the Default Sink and the Default Source here. The discovered pulseaudio servers will be listed in the list of available Sinks and Sources.
Once you selected your Sink you can try to play a sound.
[...] |
... when I select another server ... nothing happend ... the sound of application started after selection go out to local speaker ... not over the network ...
EDIT3: the firewall is down on the server and pulse is listening on the network, so it "should" work ... :
| Code: |
[root@serveur ~]# netstat -an | grep 4713
tcp 0 0 0.0.0.0:4713 0.0.0.0:* LISTEN
tcp 0 0 :::4713 :::* LISTEN
|
(ipv4 and ipv6 ...)

Networking works
In fact, the "padevchooser" wasn't working at all ... I have to use command-line ... On the Web, I found these two line who permit me to send a stream from my PC to my server :
| Code: |
pactl load-module module-tunnel-sink "server=<ip_server> sink=<sink_on_server_side> sink_name=toto"
pacmd set-default-sink toto
|
This is working, but ... the sound is not very good some times, will need some optimizations ....
Here are my new local sink (that I can select on my PC to send a stream to the server) :
| Code: |
index: 2
name: <toto>
driver: <module-tunnel.c>
flags: NETWORK HW_MUTE_CTRL HW_VOLUME_CTRL LATENCY

tunnel.remote.sink = "<sink_in_server_side>"
device.icon_name = "audio-card"
tunnel.remote_version = "16"
tunnel.remote.user = "invite"
tunnel.remote.fqdn = "serveur"
tunnel.remote.description = "Internal Audio Analog Stereo"
|
Note: this tunnel is no more in use right now.

Ok, all is working as expected (with command-line) ... but, I heart some "gap", some "little break" less than one second every 5-10 minutes (when using "module-combine" .. I'm checking if I got same behavior for a simple tunnel ...
Do you know if I can fix it ???

Did you found a solution for this little "gaps". I have the problem too.
