I've seen a similar problem. The flash plugin will send data to the default ALSA device. After using the solution at http://alsa.opensrc.org/FAQ026 (with the right sound card name from /proc/asound/cards) the flash plugin worked again for me. Unloading/reloading pcspkr (or blacklisting it) would probably work as well.
Here is /proc/asound/cards showing the PC speaker as the default card: mich...@contra:~$ cat /proc/asound/cards 0 [pcsp ]: PC-Speaker - pcsp Internal PC-Speaker at port 0x61 1 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0x44080000 irq 16 And here's the new asound.conf: pcm.!default { type hw card SB } ctl.!default { type hw card SB } The interesting thing is, pulseaudio worked without that change. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
