The bug report cited above suggests that the HDMI alsa sink is the root
of the problem.

Are you actually using the HDMI output for sound?


No.

cat /proc/asound/cards

                      HDA ATI SB at 0xfe7f4000 irq 16

So there is an USB audio device connected as well?
Unless it's my cassette tape to MP3 converter, I'm at a loss to know what it could be. I'm not aware that USB sound was an option with this PC. I'll have to see whether Gateway still have the manuals available (the PC was an E-bay purchase from an overstock company, I got no software or documentation of any kind, just the hardware).

that one with flashplayer then it might be enough to run

   modprobe -r snd_hda_intel
   modprobe -r snd_usb_audio
   modprobe snd_usb_audio index=0

as root or with sudo. You may have to log out from your desktop
environment and issue these commands on a terminal (you cannot remove
modules that are in use). After you have done this, verify that
/proc/asound/cards now lists the USB device as card number 0, then try
if you get sound output from flashplayer. The annoying thing about sound
with Flashplayer is that the browser plugin seems to be hell-bent on
using alsa's card number 0 directly; I have never managed to make it to
respect any KDE/phonon or pulseaudio setting that says otherwise.

If you want to use the Intel SB device then you can test if disabling
the HDMI sink is sufficient to make flashplayer behave:

   modprobe -r snd_hda_intel
   modprobe snd_hda_intel enable=1,0

(Verify that /proc/asound/cards lists SB as card 0 and that the HDMI
card is gone after you do that.)

If you find a configuration that works then you can make it permanent by
putting the corresponding module options in a file in /etc/modprobe.d/
to make them persistent across reboots. I recommend creating an extra
file for that rather than adding the options to an existing file. (This
approach ensures that your settings will never be overwritten by an
upgrade.)
Thanks for the detailed help. I will try the second approach first, then try to look up the documentation for the PC. There is also one other solution I found which involved some switches to the commands in grub, I have that waiting in the wings if this approach doesn't work.
I'll report back as soon as I've had a chance to try it all, but that may not be for a couple of days. 


Brian.
