One of my Debian installs is booted on different machines, I frequently move the disk between my laptop and desktop. One of the issues I encountered is that the audio levels are reset when I move between machines. Specifically the Master Front level is set to zero. I also get warnings about cards about being present during bootup. The ideal situation would be: Store the mixer settings in a per-system or per-audio-device file. Have a cron job delete mixer settings for cards that haven't been used in 6 months or so. This would help roaming folks who boot Debian from a USB key on various machines, including Internet cafes. Ideally pulseaudio would take over this job (since it is per-user) but alsa-utils needs to also do it for those who don't use pulseaudio.
Hello Paul or should I say Paps? first: your gpg key has been expired ;-) * Paul Wise [101109 14:44 +0800]: Well, just an idea: I am using netenv in such cases. You can define a per hostname dependend /var/lib/alsa. This is the place where the soundcontrols are stored. As well you can define a asoundrc (etc or $home) per hostname for the diffrent sound devices and you're done. Isn't that to complicated? Nice idea, but you know unixes are providing many solutions and are always a challenge. If one uses a stick or hd for more than one machine we can expect that user can handle those comfortable ideas with provided tools by himself, isn't it? Elimar
Per-hostname is insufficient since it is the same Debian install on one hard drive, but I am booting it on different hardware. It would meet my needs and the needs of other roaming Debian users. I think it would be exactly enough flexibility to support all users. It would be almost trivial to support this within alsa-utils and there are zero to minimal downsides for non-roaming users so I don't see why it couldn't be implemented within alsa-utils (apart from lack of time).
