Comment 11 for bug 79128

I also have this problem. Sometimes happens when switching from playing a radiostream to play a local stored mp3 or viceversa (is not reproducible though).

Here the cards I use. In the amarok the Alsa Device Configuration I have hw:Audio in the 'Stereo' field (i.e. the external USB card is the default). Sometimes amarok uses the IXP card (internal laptop sound card (laptop speakers)) though without notice.

jtocancipa@golem:~$ cat /proc/asound/cards
 0 [IXP ]: ATIIXP - ATI IXP
                      ATI IXP rev 1 with unknown codec at 0xb0003400, irq 17
 1 [Modem ]: ATIIXP-MODEM - ATI IXP Modem
                      ATI IXP Modem rev 1 at 0xb0003800, irq 17
 2 [Audio ]: USB-Audio - USB Audio
                      USB Audio at usb-0000:00:13.1-2, full speed
