I am working on android and and in our device we use ALSA.
I have enabled dmix support for andoid as by default android doesn't have this plugin enabled and soon will post it in android forum however i have run into some problems.Hoping takashi can help me out on this.
Problem is when i am trying to use dmix plugin i am not getting any sound (logs shown below).Is it because i don't have mmap mode support on my device???
If yes then can't dmix work without mmap mode??? Logs shown below:
Entered s3c24xx_pcm_hw_params, line 330
Entered s3c24xx_pcm_pointer res_value
snd_pcm_update_hw_ptr_pos xun: occured XRUN!
Normal playback and recording is fine if i dont use dmix plugin.During my normal playback and recording i don't use mmap as i preallocate DMA memory and use them.
