Hi,

I tested the patches and got everything working with minor changes.
However, there seems to be some problem with PM, occasionally ASoC is stuck with Standby mode (looking at dapm_widgets) when I start the playback. Restarting the player brings the sound back. I'll carry out some further investigation and get back to this.
Thank you for your help!
I've done more tests using the oss emulation in ALSA, and I have encountered a problem. In a previous mail Mark you mentioned this:
+/*
- Record SSC clock dividers for use in hw_params().
- */
+static int atmel_ssc_set_dai_clkdiv(struct snd_soc_dai *cpu_dai,
- int div_id, int div)
+{
- struct atmel_ssc_info *ssc_p = &ssc_info[cpu_dai->id];
- switch (div_id) {
- case AT91SSC_CMR_DIV:
/** The same master clock divider is used for both* transmit and receive, so if a value has already* been set, it must match this value.*/if (ssc_p->cmr_div == 0)ssc_p->cmr_div = div;elseif (div != ssc_p->cmr_div)return -EBUSY;break;
What happens if the user wants to change the master clock divider at runtime - for example, when changing sample rates?
I had actually a crash because of this, so I will send a patch to correct it(I simply removed it since I don't thonk it is needed).
