And if it's configurable for multiple formats, was it set for the correct one?Is there a way to verify was it set for the correct one or not?arecord -v gives what it thinks the setup is.quoted

Does the record die immediately, or hang for a few seconds and timeout?What is the difference between these two ways?An immediate failure is usually related to a "Can't do it" situation where the USB interaction to configure the device has failed, while a timeout usually indicates that the configuration at least *claimed* to succeed, but is failing to properly transfer valid data.quoted
For my hardware, I noticed that it hangs for a few seconds and gives EIO (arecord: pcm_read:2032: read error: Input/output error).Given that the usbmon output ran to several megabytes, that's tending to point at "the card was returning lots of packets, but they weren't actually the format/data that arecord was expecting.
So, is it a USB card issue? -- Thanks, Sekhar _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
