I am having a problem with audio underruns when running usrp_wfm_rcv.py I constantly get audio underruns. I have tried the "-O plughw:0,0" option suggested on this or some other list to overcome this problem, but it does not help.
When I reduce usrp_decim from 200 to about 184 the underruns go away, this I guess indicates that the issue is not related to the USRP or the USB interface as this will mean that more data is sent to the host.
The host is a powerful Pentium 2.4(running below 100% cpu load), platform is Fedora 10/GNURadio 3.1.3.
Could somebody please give me a hint on how to debug this issue further.
