Did you switch back to

You could also play with the other gpio settings.
And the last idea (at the moment):
+ /* 0db0:8810 MSI DIGIVOX ATSC (HU345-Q)
+ * Empia EM2874B + TDA18271HDC2 + LGDT3305 */
+ [EM2874_BOARD_MSI_DIGIVOX_ATSC] = {
+ .name = "MSI DIGIVOX ATSC",
+ .dvb_gpio = msi_digivox_atsc,
+ .has_dvb = 1,
+ .tuner_type = TUNER_ABSENT,
+ .ir_codes = RC_MAP_MSI_DIGIVOX_III, /* just a guess
from looking at the picture */
+ .xclk = EM28XX_XCLK_FREQUENCY_12MHZ, /* TODO */
+ .i2c_speed = EM2874_I2C_SECONDARY_BUS_SELECT |
+ EM28XX_I2C_CLK_WAIT_ENABLE |
+ EM28XX_I2C_FREQ_100_KHZ,
+ },
=> change .xclk to 0x0f.
We know that 12MHz is the right xclk setting, which means 0x07. But OTOH
the Windows drivers seems to use 0x0f instead and we don't what 0x0f
means...
Hope this helps,

I lied, it works! I must have forgotten to do run make modules_install
or something! This patch accurately states my current code changes:
http://pyther.net/a/digivox_atsc/diff-Dec-06-v1.patch
I will do more testing and try more channels. Playing the stream with
mplayer, the audio is clearly out-of-sync. But if I can the stream to a
file, it doesn't seem out-of-sync but I will do more testing and report
back.
