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?
It's a problem of either your device (e.g. USB device firmware) or the kernel. Do you get any relevant kernel error messages?
dmesg log does not indicate any such error messages when arecord fails. Is there a way to prove it as a USB device firmware issue or kernel issue? Please find the alsamixer output in the attached file alsamixer_output.png file.
