Looking at md5sums of the firmware files at dl.ivtvdriver.org/ivtv/firmware, I see that Andy is using the pre-20080701 version of v4l-cx25840.fw: 588f081b562f5c653a3db1ad8f65939a cx18-firmware/v4l-cx23418-apu.fw b6c7ed64bc44b1a6e0840adaeac39d79 cx18-firmware/v4l-cx23418-cpu.fw b3704908fd058485f3ef136941b2e513 cx18-firmware/v4l-cx23418-dig.fw 305dba74bbe5905447add8883f3ecb68 ivtv-firmware-20060701/v4l-cx2341x-dec.fw d85cb08382395390dc95ac6ebc2205f9 ivtv-firmware-20060701/v4l-cx2341x-enc.fw 99836e41ccb28c7b373e87686f93712a ivtv-firmware-20060701/v4l-cx25840.fw 305dba74bbe5905447add8883f3ecb68 ivtv-firmware-20061007/v4l-cx2341x-dec.fw d85cb08382395390dc95ac6ebc2205f9 ivtv-firmware-20061007/v4l-cx2341x-enc.fw 99836e41ccb28c7b373e87686f93712a ivtv-firmware-20061007/v4l-cx25840.fw 305dba74bbe5905447add8883f3ecb68 ivtv-firmware-20070217/v4l-cx2341x-dec.fw 9b39b3d3bba1ce2da40f82ef0c50ef48 ivtv-firmware-20070217/v4l-cx2341x-enc.fw 99836e41ccb28c7b373e87686f93712a ivtv-firmware-20070217/v4l-cx25840.fw 305dba74bbe5905447add8883f3ecb68 ivtv-firmware-20080701/v4l-cx2341x-dec.fw 9b39b3d3bba1ce2da40f82ef0c50ef48 ivtv-firmware-20080701/v4l-cx2341x-enc.fw b3704908fd058485f3ef136941b2e513 ivtv-firmware-20080701/v4l-cx25840.fw 3a4803384f749d644ee1f1ca9dcb12fa HcwMakoB.ROM My system has files matching ivtv-firmware-20080701 and the intermittent "tinny" audio issue on my PVR-150 (I use line-in). This install is from Nov 2008, and my previous install (~Feb 2007) on the same system did not have the audio issue. I will try reverting to ivtv-firmware-20070217/v4l-cx25840.fw and see if my audio issue goes away.
