Detailed changelog between 1.0.21 and 1.0.21a releases

Mixer API:

• Add Speaker and Beep names to the weight list. Added strings “Speaker” and “Beep” to the weight list so that the entry appear in more appropriate positions

PCM API:

• Change the hw_params determination order. In snd_pcm_hw_params_choose(), set the buffer size before the perio size and time as default. This will give more useful configuration fo most of apps, ie larger buffer size. For apps that require the old behavior, now the function checks the environment variable $LIBASOUND_COMPAT. If this variable is set to non-empty, the hw_params is determined in the old way, first perio then buffer sizes

Configuration:

• Change dmix.conf to accept user configuration from defaults.dmix..xx. An attempt to fix problem described in reverted patch “Fix driver con parsing in snd_config_hook_load_for_all_cards()”
• Revert “Fix driver conf parsing in snd_config_hook_load_for_all_cards(). This reverts commit 96da0c842d14b40ce8e37726b259229634b3aa21. This way of fix brokes card-specific configuration loading. See http://bugzilla.redhat.com bug#521988 is way to handle this problem. to fix the dmix configuration file.
