ALSA: hda - Add quirk for Dell Inspiron 19T using a Conexant CX20582
RFC PATCH 1/1 ALSA: hda - Add quirk for Dell Inspiron 19T using a Conexant CX20582
Add a quirk for all-in-one computer Dell Inspiron One 19 Touch to have proper HP and Mic support.
---
Hi,
I have a Dell 19T all-in-one computer, which has audio problems by default:
- speakers works OK
- no jack detection, no audio in HP
- internal or external Mic not working
If I specify model=ideapad, the problems go away. But Mic boost appears as an "Analog Mic Boost Capture Enum" between 0 and 40dB instead of a normal bar control in alsamixer.
I also tested model=dell-vostro, laptop, and dell-laptop, and they give worse results. There's no BIOS update available from vendor ATM.
I'm using kernel tree sound-2.6 on branch master.
I'm attaching alsa-info.sh output with and without model=ideapad in addition to the patch.
Regards,
Anisse

Thanks. I applied the patch as is, as a quick fix for now.
