Prev: Possible methods for the kernel to terminate a process
Next: PM: Avoid losing wakeup events during suspend

I have an application using the on-board sound card mic which should
send it's data to the USB card for relay to a Sofweare Defined Radio as
2 quadrature signals digital (I/Q) for transmission.
On the receiving side it can take data from the Radio at up to 192K
sample rate --> program --> Speaker on the on-board sound card - that
works fine.
Transmit fails, dmesg output with 48K sample rate set is:-
[509686.177169] ALSA sound/usb/clock.c:214: 6:2:3: endpoint lacks sample
rate attribute bit, cannot set.
[509686.187920] ALSA sound/usb/clock.c:214: 6:2:1: endpoint lacks sample

There are many devices that have only one sample rate or that have one
sample rate per alternate setting. This doesn't deserve a message, much
less a warning.

This device uses a global clock rate according to the data sheets.
So, record rate must equal playback rate.

The application uses the on-board HDA Intel sound card for Mic and
Speaker output.
For receive, data from the receiver goes to the E-MU 0404 USB at ~10
KHz where it is digitized then processed by the application and comes
out the speaker as audio - that works at 48K, 96K and 192K sample rate.

For transmission you speak into the mic and it's processed by the
application, digitized and sent to the E-MU 0404 USB where it's
converted to audio that is used to modulate the transmitter and out to
the antenna - that doesn't work even at 48K sample rate, i.e there is no
output from the E-MU 0404 USB.

On another box with the Terratec Aureon 5.1 USB card, it works both ways
at 48K sample rate though the audio going to the transmitter is
insufficient to drive the transmitter to the expected output.
