[alsa-devel] unsupported variant of snd_hda_intel
Hello,
I have an Acer Aspire 4736G laptop. The soundcard that is shipped in this laptop is intel-hda based as shown (actually it's a realtek):
cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0x9b300000 irq 46
Basic sound output is correct but few feature are missing: - internal mic seems to be found but do not works. - sound output stop working when trying to send it using HDMI output - heads do not work when plugged neither when forcing pulseaudio to use it.
I have an ubuntu 10.10 which is shipped with alsa 1.0.23. I have googled around and tried loading the snd-hda-intel with several parameters () as found in HD-Audio-Models.txt to no avail.
cat /proc/asound/pcm 00-00: ALC888 Analog : ALC888 Analog : playback 1 : capture 1 00-01: ALC888 Digital : ALC888 Digital : playback 1 00-03: NVIDIA HDMI : NVIDIA HDMI : playback 1
Where can I begin to help implement the support for this sound card? I have very skills in developement in general but am ready to try if it is not to hard (I supose I can use previous code for similar models).. I just need a shepherd.
Thanks

His 4736g work with model="acer-aspire-4930g"
I don't know to read chineese but setting options to model="acer-aspire-4930g" doen't help. internal microphone still dont work... I am not sure if it is alsa or pulseaudio related. How could I test the internal mic by passing pulseaudio?

Install pavuctl, the pulseaudio volume control, and turn off this device for pulseaudio. It will then use alsa by default. You might have to fiddle with applications to be sure *they* expect to use alsa instead of pulseaudio as well.
