Mark in my case it is not restarting the audio stream(though it is trying to call trigger again for restarting)
because in s3c_snd_lrsync function again i am getting time out(ETIMEDOUT).
iiscon = readl(s3c_i2s.regs + S3C_IISCON);
if (iiscon & S3C_IISCON_LRI)
break;
This LRI register bit is not getting set properly causing timeout.How this situation is not coming always(4/10)??
And who should suppose to set it?
If my machine driver had a problem then this should have come always??
Thanks for your reply.
