Hello,
The attached file is a patch to support the sound hardware in the Samsung NC10 mini notebook. The Samsung NC10 is and Intel Atom-based notebook with Realtek ALC272 HDA codecs. Sound is supported partly in Linux depending on ALSA version, but there were always some issues (wrong mixer behaviour, PC beep always muted, ...). This patch tries to solve most of these issues. I updated the patch so it would work using the alsa-driver-20090509 snapshot from ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/ (originally developed from alsa-driver-20090416 snapshot).
Fixes: - mute internal speaker / microphone when plugging in external headphone / microphone - stereo capture from external microphone - separate volume controls for headphone and internal speakers + "Master" for both - "PC Beep" mixer control - "Mic boost" and "External mic boost" controls - ...
A few issues remaining: - Recording PCM output does not work yet. It works on the version of Windows that comes with the NC10. - When choosing recording source "Internal Mic" while an external microphone is plugged in, the internal microphone will be used instead of the external one, as it should. However, when plugging in the external microphone after choosing the recording source setting, it WILL override the internal microphone.
When replying, please note I am not on list.
