[alsa-devel] ALSA underruns for S32_LE format

[kuldeep ghan]

Hi,
 Thanks Jassi, I dont my System is too slow, I have dual core processor,
1.5GHz. no CPU consuming process running on it.
 I Shall confirm if it does not support S32_LE.. Is  there any means by
which I can confirm the same without
 going through Codec Driver??
