I have a working sound support for the mx31moboard boards available here: http://github.com/retornaz/linux/commits/moboard-sound It's basically Sascha mc13783 codec driver (from his git tree) rebased on 3= .2 = and some mx31moboad specific code. I can playback & record sound on our board (2 channels@16Khz) with the sdma. Sascha, do you have any plan to upstream the mc13783 codec driver ? = Thanks, Philippe From mboxrd@z Thu Jan 1 00:00:00 1970 From: philippe.retornaz@epfl.ch (Philippe =?ISO-8859-1?Q?R=E9tornaz?=) Date: Wed, 25 Jan 2012 16:45:40 +0100 Subject: [RFC PATCH] ARM ASoC: add sound driver for imx27pdk using mc13783 codec In-Reply-To: <201107271028.09928.philippe.retornaz@epfl.ch> References: <1310131491-625-1-git-send-email-J.Lambrecht@televic.com> <4E1711EA.5070209@televic.com> <201107271028.09928.philippe.retornaz@epfl.ch> Message-ID: <2667396.yifGumf5nD@laptop> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi > Le vendredi 8 juillet 2011 16:19:22, Lambrecht J?rgen a ?crit : > > indeed, doesn't work at all.
