Hi ALSA SOC,
I am using a OMAP3 + TWL4030 combination with ASoC
in the sound/soc/omap/omap-pcm.c
DMA channels are being freed after unlinking in the omap_pcm_hw_free
function
Which is causing a crash during applications
So, stopping the DMA channels before unlinking resolves the issue.
here is the patch that solves the issue
diff --git a/sound/soc/omap/omap-pcm.c b/sound/soc/omap/omap-pcm.c
index e9084fd..679e384 100644
--- a/sound/soc/omap/omap-pcm.c
+++ b/sound/soc/omap/omap-pcm.c
@@ -116,6 +116,7 @@ static int omap_pcm_hw_free(struct snd_pcm_substream
*substream)
if (prtd->dma_data == NULL)
return 0;
+ omap_stop_dma(prtd->dma_ch);
if (!cpu_is_omap1510())
omap_dma_unlink_lch(prtd->dma_ch, prtd->dma_ch);
omap_free_dma(prtd->dma_ch);
Is this ok or is there any better way out

Thanks,
