--------------------+-------------------------------------------------------
 Recently upgraded from 6.4 to 6.5 with the new alsa-lib-1.0.21.
 After which sound apps didn't work like they should.

 Here's my hardware:

 bash-4.0$ cat /proc/asound/cards
  0 [SB             ]: HDA-Intel - HDA ATI SB
                       HDA ATI SB at 0xfbbf4000 irq 16
  1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                       HDA ATI HDMI at 0xfbde8000 irq 19


 One issue that lead to a solution was the error mpd returned when
 launching
 "ALSA lib conf.c:4626:(snd_config_expand) Expand error (walk): File
 exists"

 Also alsamixer failed to show a PCM 'device'.

 None of the above problem happened with 6.4 running alsa-lib-1.0.18.

 It seems others have had similar problems:

 Reporting is as alsa-lib-1.0.21 being broken and requesting BLFS to
 upgrade to 1.0.21a.
