Subject: [PATCH] snd_hda_codec_realtek: enable ALC271 for Acer laptops
Date: Thu, 07 Apr 2011 19:38:27 +0200 [thread overview]
Message-ID: <201104071738.p37HcSFX019185@vivaldi20.register.it> (raw)
This quick fix to the Realtek HD Audio driver enables configurable support for the ALC271 type commonly found on some Acer laptops (e.g. Aspire 5745G).
Normally, the driver would fall back to BIOS auto-probing. However, the "model=acer" parameter can be passed on the boot command line to enable such support. Otherwise, it is quite common that the internal microphone does not work.
