Interesting…

> OK, now run the same pipeline with the new "drift-tolerance" property added:

gst-launch-1.0 -v alsasrc device=hw:XFi latency-time=20000 buffer-time=800000
drift-tolerance=25000000 ! audioconvert ! audioresample ! alsasink
device=hw:XFi sync=true
0:00:00.068520914 24723  0x852f1a0 ERROR           GST_PIPELINE
./grammar.y:432:gst_parse_element_set: no property "drift-tolerance" in element
"alsasrc0"
WARNING: erroneous pipeline: no property "drift-tolerance" in element
"alsasrc0"

There is no drift-tolerance option in alsasrc module, but there is one in
alsasink module:

gst-launch-1.0 -v alsasrc device=hw:XFi latency-time=20000 buffer-time=800000 !
audioconvert ! audioresample ! alsasink device=hw:XFi drift-tolerance=25000000
sync=true

Tthis last pipeline is running with sound.
