2987	alsa-lib-1.0.23	zoyd	blfs-book@…	"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.
