[alsa-devel] Trying to support hda-intel ALC883_CLEVO
I have a Clevo M600 notebook, which comes with Realtek's HDA Intel audio chip. 'lspci -vn' says:
00:1b.0 0403: 8086:27d8 (rev 02) Subsystem: 1558:0660 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at 6c340000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable- Capabilities: [70] Express Unknown type IRQ 0 Capabilities: [100] Virtual Channel Capabilities: [130] Unknown (5)
Linux 2.6.20 (Gentoo's gentoo-sources-2.6.20r4) recognizes it as an ALC883 chip, but no parameter combination would make the sound work properly (and that includes 'model=clevo'). As this module ships, no output would come from the built-in speakers, and the headphone volume was miserably low.
patch_realtek.c supports vendor=1558 device=0660, but only as a ALC880 chip. However, mine *is* an ALC883 vendor=1558 device=0660.
After copying the ALC880_CLEVO support code lines into a new ALC883_CLEVO (and changing every occurence of ALC880 to ALC883 in that new code block), recompiling the kernel and loading the snd-hda-intel with model=clevo, almost everything started working fine. I mean, sound comes as perfectly as it can through the built-in speakers, and the built-in mic also outputs its sound through these speakers.
However, I can't capture anything. Alsamixer shows no capture device at all (although all playback devices appear to be present).
This is very strange to me, as the built-in mic really *does* output its sound through the speakers.
As you can probably see, I don't know anything about sound chips. I just did what seemed understandable (to me) to add proper support for my ALC883_CLEVO device.
Thank you very much if you can help me solve this issue, as I really need to speak with my family and girlfriend far, far away.

Could you download and run http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh and post the resulting link? This script will dump information on your system that we can use to debug this.
Also, for the alc883 in the current code (without your patch), could you try loading with "model=laptop-eapd"? Try with the most recent snapshot from here: ftp://ftp.suse.com/pub/projects/alsa/snapshot/
