According to errata i.MX 233 DAC DMA halts unexpectedly. I tried https://github.com/ITserve/imx23-audio imx23-audio driver (linux kernel 3.10) but it halts, as documentation says; After few messages: DAC overflow detected appeared, DAC underflow detected appears, which in fact means DAC DMA halt. The given solution doesn't work. Look's like the problem in this posts:Re: subtle bug with alsa driver backend or mxs-dac driver.
Re: i.MX233 sound in 3.x kernel?Does any one make mxs-builtin-audio work? Do You have any suggestions?
Thanks in advance:)
