[Pkg-alsa-devel] Bug#849203: Bug#849203: libasound2: ALSA_PCM_DEVICE environment variable is ignored

[Leszek Godlewski]

Hi Elimar,

If that is the case, why does ALSA_PCM_CARD work without such preparation?
/usr/share/alsa/alsa.conf contains a similar block for the card, yet it
isn't needed in /etc/asound.conf.

I will try it anyway and let you know if it worked, thanks!
