Hi Jaroslav.
I updated the alsa-lib from git, and "aplay -L"
no longer shows some PCMs it used to list before.
I tracked this down to this commit:
---
commit 97d25c0766405453d3c298bd51dd4916121a4f6a
Author: Jaroslav Kysela <perex@xxxxxxxx>
Date: Fri Aug 20 10:31:17 2010 +0200
namehint: Evaluate more possibilities for hw devices
---
Attached are the outputs before and after the commit.
So why some devices are now missing?
