Hello,
I run 'alsactl restore' on a machine with 2 sound cards -- a built-in Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02) and a non-built-in Yamaha Corporation YMF-724F [DS-1 Audio Controller] (rev 03) -- and get the following message:
Unknown hardware: "YMF724F" "SigmaTel STAC9700,83,84" "AC97a:83847600" "0x1073" "0x000d" Hardware is initialized using a guess method
As a consequence the volume levels of the Yamaha card do not get restored to the levels stored in /etc/asound.state. The volume levels of the built-in card however are properly restored. The asound.state file has been created by executing 'alsactl store'.
The kernel has been built with support for ALSA. I've built and installed the kernel modules for both cards (not the ones in the alsa-driver package but those that come with kernel version 2.6.30.2). Any ideas why alsactl cannot find the hardware it has previously identified as "YMF724F", "SigmaTel STAC9700,83,84", and so on?
The logic of alsactl is to restore the state from /etc/asound.state if it is valid. It seems like the set_controls() function in alsactl/state.c returns an error code for a reason.
Could you try to compile the latest alsa-utils snapshot (http://www.alsa-project.org/snapshot/) and run './alsactl -d restore' in alsa-utils/alsactl directory? A warning (fail reason) should be printed.
I've attached a bash shell script that I used to download, configure, compile, and run alsactl. I've also attached a .log file with stdout and stderr that I got while executing the script.
Thanks. I've added more debug print lines to state.c. Could you rerun your script and append also '/etc/asound.state' file and output from 'alsa-info.sh --no-upload' to your output tarballs? Send me this tarball privately or just an URL to this list.
Thanks, Jaroslav
