I've built a small HTPC and had to add suspend/resume support in ice1724 driver. There seem to be 3 existing bugs related to that: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4413 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3748 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2314 Due to hardware (un)availability, I only enabled the fix for Audiotrak Prodigy HD2 card, which is installed in my HTPC. However, most of my code should be reusable in the future on other ice1724-based cards as well (as long as people add card-specific peices of code). The fix is currently based on ALSA 1.0.20 and works on my MythBuntu 9.04 HTPC (using 2.6.28-11 kernel). The following files have been modified: alsa-kernel/pci/ice1712/ice1712.h alsa-kernel/pci/ice1712/ice1724.c alsa-kernel/pci/ice1712/prodigy_hifi.c Now, I'm a complete newbie in Linux development and not sure I can safely rebuild latest Linux Kernel under MythBuntu, etc. Are there any resources for people like me to read? I want to provide the patch without destroying my computer a hunder times, but also make it more convenient and safer for ALSA maintainers. Thanks, Igor
