Original commit message from CVS: * ext/alsa/gstalsa.c: (gst_alsa_probe_hw_params), (gst_alsa_set_hw_params), (gst_alsa_set_sw_params), (gst_alsa_start_audio): - don't call set_periods_integer anymore, it breaks the configuration randomly - call snd_pcm_hw_params_set_access directly instead of using masks - don't fail if the sw_params can't be set, just use the default params and hope it works. Alsalib has weird issues when you touch sw_params and does no proper error reporting about what failed. * ext/alsa/gstalsa.c: (gst_alsa_open_audio), (gst_alsa_close_audio): make our alsa debugging go via gst debugging and not conditionally defined * ext/alsa/gstalsa.h: add ALSA_DEBUG_FLUSH macro * ext/alsa/gstalsaplugin.c: (gst_alsa_error_wrapper), (plugin_init): wrap alsa errors to be printed via the gst debugging system and not spammed to stderr
