Re: [linux-audio-dev] configuring ALSA support in linux 2.6.11

Hi, Thanks , i'm using linux kernel 2.6.11(for h4 from www.kernel.org). Yes thats right. Do you suggest me anything to test or verify in driver as default config file for this target (omap_h4_2420_defconfig) does not have ALSA configuration macro to configure.
