OK, so I tested both s-video and composite inputs. I get video for
s-video, but not composite. The video seems to flicker a little bit
in tv time. I just have standard rca cables plugged in for audio,
but I can;t get any sound.
I tried changing the "tuner-type" to 0xc2, 0xc4, and 0x61. All
three gave the same results.

So the good news was that the s-video was working. I want to make sure that I hooked up the sound correctly. I can't imagine that there is any other way than the rca cables. So what is next?
Switch to this tree http://linuxtv.org/hg/~stoth/cx23885-audio and try again with the svideo and audio tests.
Mijhail Moreyra wrote some HVR1500 audio patches, which I have not tested yet. Do these produce audio for you via the svideo and breakout RCA audio input cable?Look at how the HVR1500 analog tuner is setup in this tree, it may help - especially with the tuner setup.
The only things that I can adjust in cx23885-cards.c is the "tuner-type" I've tried various suggestions, but had no luck. Are there other parameters that can be changed?

I have been using the cx23885-audio branch the entire time. I still do not get audio.
I have a thought about the setup. I was looking at this part of the HVR-1500 driver
.input = {{
.type = CX23885_VMUX_TELEVISION,
.vmux = CX25840_VIN7_CH3 |
CX25840_VIN5_CH2 |
CX25840_VIN2_CH1,
.gpio0 = 0,
}, {
.type = CX23885_VMUX_COMPOSITE1,
.vmux = CX25840_VIN7_CH3 |
CX25840_VIN4_CH2 |
CX25840_VIN6_CH1,
.gpio0 = 0,
}, {
.type = CX23885_VMUX_SVIDEO,
.vmux = CX25840_VIN7_CH3 |
CX25840_VIN4_CH2 |
CX25840_VIN8_CH1 |
CX25840_SVIDEO_ON,
.gpio0 = 0,
} },
The DVICO FusionHDTV5 board has the following
[CX88_BOARD_DVICO_FUSIONHDTV_5_GOLD] = {
.name = "DViCO FusionHDTV 5 Gold",
.tuner_type = TUNER_LG_TDVS_H06XF, /* TDVS-H062F */
.radio_type = UNSET,
.tuner_addr = ADDR_UNSET,
.radio_addr = ADDR_UNSET,
.tda9887_conf = TDA9887_PRESENT,
.input = {{
.type = CX88_VMUX_TELEVISION,
.vmux = 0,
.gpio0 = 0x87fd,
},{
.type = CX88_VMUX_COMPOSITE1,
.vmux = 1,
.gpio0 = 0x87f9,
},{
.type = CX88_VMUX_SVIDEO,
.vmux = 2,
.gpio0 = 0x87f9,
}},
.mpeg = CX88_MPEG_DVB,
},
Notice that .vmux and .gpio0 are set very differently. Evidently these values were set according to the rules
/*
GPIO[0] resets DT3302 DTV receiver
0 - reset asserted
1 - normal operation
GPIO[1] mutes analog audio output connector
0 - enable selected source
1 - mute
GPIO[2] selects source for analog audio output connector
0 - analog audio input connector on tab
1 - analog DAC output from CX23881 chip
GPIO[3] selects RF input connector on tuner module
0 - RF connector labeled CABLE
1 - RF connector labeled ANT
GPIO[4] selects high RF for QAM256 mode
0 - normal RF
1 - high RF
*/
which are found in the dvico fusionhdtv 3 section. Of course, I could just be grasping at straws. I have included Michael on this email to possibly shed some light on this. I figure that .vmux and .gpio0 have to be set differently so that it uses settings from the dvico board, but then if I changed those values, it wouldn't be using settings from the cx25840 driver.
