Same issue for me (with audacity) but only after upgrading yesterday for the first time after Christmas. After rmmoding snd_usb_audio and snd_usb_lib audacity worked fine again and it was possible to use the (video facilities of) webcam again.
I guess either the lock occurs in pulseaudio or in the kernel modules.
