Thanks
Hi ALSA developers,
does it make sense to apply the patch to HEAD? I don't have a Hammerfall handy and can not test it.
Thanks for cooperation.

On Sun, 11 Nov 2007 the mental interface of Frank Heckenbach told:
Package: alsa-tools-gui Version: 1.0.13-1 Severity: normal Tags: patch
We are using Hammerfall DSP cards. After booting, their audio output remains silent until hdspmixer is started. No interaction in the GUI of hdspmixer is necessary to unmute the first HDSP card; however, further cards are only unmuted when activating the respective GUI page ("2", "3"). Apparently, hdspmixer does some automatic initialization of the card when activating the page.
Since we'd like to have a fully automatic startup, the following patch activates the page for each existing card on startup, thereby initializing them. There are surely more elegant solutions, but this patch is tested and solves the problem for us.
