Linux: OMAPL138 LCDK ALSA support

Hi,

Please post the relevant parts of your board file. Also a bootlog (dmesg) would be good.

Best Regards,
Yordan

Hi,

Thank you very much for your reply.

I am unable to get you "relevant parts of your board file". However I am sending the dmesg. I am using omapl138 lcdk.

Hi Yordan,

One more thing I should mension. Though my board is OMAPL138 LCDK the "arecord -L" shows my sound card is
DA850/OMAP-L138 EVM.

Thanks & regards,
Jagadish
