September 12 in bug tracking system, Adobe was reported that a critical error in Flash Player 11 for 32 – and 64-bit platforms. Bug is that Flash can not record sound with the “Default device” to ALSA.
Many popular Linux distributions to a given query “Default device” is forwarded to the PulseAudio-ALSA-plugin. At the same time, Flash is trying to use direct access to an audio device, so if the system as PulseAudio instead of simply relying on PulseAudio, Flash creates a list of audio devices on their own and trying to work with them directly. The path is either correct the error in the use of plug-PulseAudio-ALSA, or embed in support PulseAudio.
