That's a very interesting discovery you've made... and this little debug output also confirms this, when I tried it on my card: ivtvctl -d /dev/video0 -q 0 (as default after loading the modules) Jul 25 21:02:22 myth cx25840: set audio input (0) Jul 25 21:02:22 myth cx25840: Status: 0x03 (REV_ID, Revision ID.)

When I had the problem before with no audio on tuner 0, it would say "mono" as audio mode and not detect the standard. Still don't know why it suddenly worked, with input 0.
