Subject: [PATCH] alsactl: fix the nested iteration
|
|

There may be nested iterations for hw: card names.
|
|
Handle this card name in snd_card_iterator_sinit().
|

|
|
BugLink: https://github.com/alsa-project/alsa-lib/issues/142
|
|
Fixes: eefc2c6 ("alsactl: use card iterator functions for all card loops")
