[alsa-devel] mxc-spdif delay: miss 1-2s at the beginning of the song
Dear all,
I'm facing a delay during startup missing 1-2s of the song when i'm using mxc spdif with aplay. I guess its a problem with spdif synchronization. If i put a msleep(1000) at the end of the function mxc-spdif.c:mxc_spdif_playback_start, the playback is ok.
Is there anyone who already faced this issue? BR.

Dear all,
I had some progress concerning spdif various issues (alsactl store lock, rx to tx support). Here is in attachment the patch.
Concerning the music startup i still have some issues with sync. If there is someone who can help me out with this, i will be pleased to work on this issue. IMX documentation is not really clear enough to me. Especially for the config SPDIF_SCR/TxFifo_ctrl. For now i put a delay in playback start but this is not clearly fixing the issue and this is not a solution for me.
Best regards.

Are you sure that the problem isn't that the receiver is slow to lock on?
