Great work and much appreciated!

Thanks to you helping with the omnithread problem I had on Leopard I now
have usrp_wfm_rcv_nogui.py working with a recently delivered USRP + TV Rx.
And am now listening to BBC Radio 4 FM broadcast with this. Although the
audio output is really low with volume turned up full on my Mac. Is there
any way I can set the audio gain in GR?

The GUI examples don't work for me either and I get a lot of the following
messages in /var/log/system.log:

Jan  3 21:21:24 rhys kernel[0]: USBF:    11844.563
AppleUSBEHCI[0x6c51800]::Found a transaction past the completion deadline on
bus 0xfa, timing out! (Addr: 2, EP: 6)
 
Although radiogui.py and stereo_rcv_gui.py from the following site appear to
work:

http://www.nd.edu/~jnl/sdr/stereo-fm.shtml

I say "appear" as the GUI seems to function and I get noise. Haven't spent
much time looking at the configuration of these scripts yet but suspect
they'd need tweaking for my hardware configuration. And perhaps the reason
they work at all is down to them using flow_graph instead of top_block as
the GR GUI examples do.

Many thanks,

Andrew
