Launching a 2.2 r16911 fedora 25 server (xterm and firefox start-childs) and connecting with 2.2 r16869 win64 client.
When I started a sound tab in the firefox start-child, the sound didn't start (had to use the menu to manually start, which worked).
Initial server output (no logging enabled) showed:

Disconnecting then reconnecting the client, the sound did initialize client-side (left the same firefox tab running), and there was less output.

Shutting down the server then restarting (a couple of times), and reconnecting the client in each case with -d sound, I got the same... and in none of the restarts did the sound fail to start.
These warnings are not from xpra:
ERROR: Pipeline doesn't want to pause. ERROR: from element /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Could not open audio device for playback. Additional debug info: gstalsasink.c(863): gst_alsasink_open (): /GstPipeline:pipeline0/GstAlsaSink:alsasink0: Playback open error on device 'default': No such file or directory
You can make that clearer by running your app from an xterm, the log output will show up there. And we don't use alsasink on the server unless you enable microphone forwarding and also change the default sink configuration (unlikely).
Maybe your app is using a hard-coded device name of "default"? Do you even need to specify a device?
This was changed for 2.1 in #1141.
The actual device name to use can be found in these environment variables which are exposed to all client applications (start=, start-child=, etc):
$ env | grep XPRA_PULSE XPRA_PULSE_SOURCE_DEVICE_NAME=Xpra-Speaker XPRA_PULSE_SINK_DEVICE_NAME=Xpra-Microphone
So you could use those values and fallback to "default" if you wish.
Retesting (finally) with 2.2 r17270 fedora 25 server... I get the same env | grep XPRA_PULSE results that you indicate.
I do still see the not-xpra errors though.
I'm also now finding that the legacy: wav sound is only lasting about 1-3 seconds before dropping.
Using firefox 55 on OSX 10.12 for an html5 client.
Going through all the options.
http stream: mp3, I get no sound.

And in the Console(s).

Again... no sound with any of those remaining codecs.
Tried checking the Debugging box of the connect.html page, but I couldn't spot anything other than do_paint and 'received a draw packet' logs... and had to kill the server to sort through those because connections from another client (with the debugging on) triggered the client to 're-connect' and steal the server back... and continue streaming logs.
I'll pass this to you to decide if it should be looked at before or after the firefox clipboard issues (#1461)
I do still see the not-xpra errors though.
Did you figure out where they come from? What is your server command line? Did you try starting your application from an xterm?
I'm also now finding that the legacy: wav sound is only lasting about 1-3 seconds before dropping.
Works ok here.. Firefox 56, OSX 10.12, javascript console shows nothing after audio start of aurora wav stream and the speaker icon remains on the tab.
When I try the http stream: mp3, I get no sound.
I get:

Interestingly though, when I shared the session back to the python client (OSX 10.12, 2.2 r16657) I am actually seeing the not-xpra warning as well, but the sound is working fine.

In fact, I'm getting that error even with only an xterm start-child (upon connection with a python client).
I suppose that means that the ticket can be closed and all the Firefox html5 sound issues are not at all related?
I'll pass this to you to think whether we should just open another ticket about Firefox sound, or just edit the Summary? (Sloppy, but most of the ticket has been output from Firefox sound ... mostly most anyway.)
xpra --no-daemon --bind-tcp=0.0.0.0: --start-child=xterm --start-child=firefox start :13 --html=on
As per comment:1 and comment:3, start your application (ie: Firefox) from an xterm and the alsasink messages will go to the xterm instead of the xpra server log. Those are not from xpra.
And BTW, why does the ticket title mention "tabs"? Is this relevant?
Server side, I'm seeing all the messages you're mentioning except the one you specified.
Which one? The exact messages depend on which codec is selected.
Console logs (even with the debugging box checked on connect.html) doesn't show any indication of receiving sound packets with the http stream: mp3 though.
It shows up fine here. (reminder: this one is only meant as a last resort for IE which is retarded and can't handle anything else..)
I'm also now finding that the legacy: wav sound is only lasting about 1-3 seconds before dropping.
Works fine here. If there isn't enough bandwidth, I would expect the browser to try to buffer again before resuming. There might be some messages in the javascript console output if you enable debug. (as you have noticed, there is no debug filtering at the moment: #1685)
My own testing:
If there is still a problem, I don't know where..
r17416 also fixes a small bug which allowed blacklisted options to be shown in the codec options, it only occurred if you navigated back to the connect page from the client.
