I have a Dell optiplex running Slackware 14.2. I have installed
freshplayerplugin-0.3.9.tar.gz
so that firefox can use
flash_player_ppapi_linux.i386.tar.gz

Recently I bought a Dell USB soundbar. When it is plugged in, "alist -l"
shows that it is card 1 (card 0 is the built-in Intel speaker).
I created $HOME/.asoundrc containing
pcm.!default {type hw card 1}
ctl.!default {type hw card 1}

vlc uses card 1, in particular if it is started using an "m3u" button at
"www.internet-radio.com". So do audacious, mocp, xmms.

Many other music websites use flashplyer. I'll use "www.accuradio.com" as an
example. Activating a stream causes it to be played on the Intel speaker.
I looked at the html for the page with the player control. I didn't try to
wade through it, but it contains a line with the text "AccuRadio requires
Adobe Flash".

For another example, "www.radio.pervii.com/en/Classical/245695.htm" contains
a player, which plays to the Intel speaker. Right clicking on the control
pops up a menu with a "copy audio location" button. This can be pasted,
and is "http://79.111.14.76:9113/;". Invoking vlc from a terminal window
with this as an argument plays the stream on card 1. The html source contains
the snippet init('yt_player_show'), so this might use yt_player.

Is there some method for configuring freshplayer to use card 1?

You should ask that your post be moved to the Slackware section so that it gets more attention/possible solutions.

I suggest you look at pavucontrol or kmix and see if you can change which device the stream is going to.

I would like to move the thread to Slackware, but the LQ FAQs don't mention
anything about how to do this.

Slackware doesn't have USE flags or systemd. "pactl list" shows that
pulseaudio is running. It also shows that Sink #0 is the SoundBar, and
Sink #1 is the built-in speaker. I don't know if freshplayer uses pulseaudio.

suggests that Slackware has a tendency to avoid it.

I don't like desktops and am a died in the wool fwvm2 user. As a Slackware
fan, I subscribe to the philosophy that if any distro can do it then
Slackware can, even if it takes a while.

solved the problem in 2014 by modifying "/etc/adobe/mms.cfg".
This doesn't exist in the freshplayer installation. I read on
another web page that it has been replaced by "settings.sol".
There is such a file in
"~/.macromedia/Flash_Player/macromedia.com/support/flashplayer/sys".
It is a binary file, and there doesn't seem to be a command line utility
to edit it.

The problem might be connected with flashplayer using Intel
graphics acceleration.

I just "reported" this thread and asked that it be moved to the Slackware forums. Shouldn't take too long.

I'm a fvwm2 user as well, only on Gentoo. (Former and sometimes Slackware user)

This was the case before 14.2, however, it was added during that development cycle and is the default sound server/daemon/etc (not sure the proper name for it). Unless you changed your system's defaults, it is likely running pulseaudio.

Now, I haven't used freshplayer, but the first thing I would check is to run pavucontrol and verify that the correct sound card is selected for the output.

Using pavucontrol to select the SoundBar as the fallbacck device solved the
problem. The relevant documentation can be found at
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/DefaultDevice/

In accordance with
https://superuser.com/questions/1157370/how-to-configure-pulseaudio-to-input-output-via-alsa
I changed ~/.asoundrc to contain
pcm.!default pulse
ctl.!default pulse
first, although this might no longer be necessary.

Congrats on getting it fixed!

This shouldn't be needed as it is in the system /etc/asound.conf. You should be able to remove that file without issue (assuming you didn't change /etc/asound.conf).

I subsequently discovered that this already was on the web:
