SNDRV_PCM_IOCTL_READI_FRAMES returns EIO

[Muni Sekhar]

Hi all,

I am using a USB sound card(snd-usb-audio), and it fails while doing
the audio recording "arecord: pcm_read:2032: read error: Input/output
error".

 I noticed recording(arecord) audio data on a USB sound card fails at
SNDRV_PCM_IOCTL_READI_FRAMES is giving EIO.

Can someone please clarify when the kernel returns EIO for Ioctl
SNDRV_PCM_IOCTL_READI_FRAMES? and is there a workaround for this?

Output of the alsamixer is attached.

Thanks,
Sekhar
