I am testing my audio driver on spear platform.During recording I am
getting two issues.
1. Overrun issue
2. pcm_read error
I am using arecord for capturing data.
#arecord -f dat > t
overrun!!! (at least 32.949 ms long)
Overrun issue: The issue is only reproducible if we try to record for
more than 40 sec.The strange part is that Instead of overrun condition
it will record complete data for 10sec.(This is verified with the number
of bytes recorded).
So could you please let me know whether this is an error condition or
just a warning.
pcm_read error: For this I have seen a bug is locked in the
bugzila(*Bug 472469* <show_bug.cgi?id=472469> -arecord: input/output
error ). and the status is closed saying insufficient data.
Could you please let me know what is the meaning of this bug? Is it
like, data is not available in the buffer and pcm_read from the user
space fails? But why this situation will
