I should be able to "modprobe tlv320aic3x" to install the tlv320aic3x
driver for my Flex-1500 sdr ham radio. I ordered a TLV320aic33EVM-PDK
Analog Evaluation (EVM) Kit from Texas Instruments which is the same as
the audio portion of the Flex-1500. They both use the TAS1020B USB 8051
Microcontroller to bridge from USB to SPI, I2C data, and I2S, AC97
Audio. I don't know if all of the drivers are present for the TAS1020B,
but this is what I get from the system when I plug them in:

At least part of the driver is working, but I still need the driver for
the TLV320AIC33 chip. The [i2c] [PATCH] add TI TLV320AIC33 audio codec
support is dated Apr 11, 2007 which was about 5.5 years ago! and should
be included in the drivers for Linux. What package do I need to install
to get these drivers?
The following is from Texas Instruments:
Hi Frank,
The driver for the AIC33 is part of the standard Linux kernel. You can
find it under sound/soc/codecs/tlv320aic3x.c in any standard Linux
distribution.
I'm not sure which other parts you wanted a driver for. The EVM also
contains a TAS1020B USB controller. It is used to bridge from USB to
I2S. While this makes it easy to evaluate the device by connecting it
to a host PC, I doubt that it gets used as such in any actual product.
In any case, that device has its own support page with links to firmware
and drivers.

Please let me know if you have any questions.

Subject: [DRIVERS] need linux drivers for all parts of the
TLV320AIC33EVM-PDK board.
Dear sirs:
I purchased a TLV320AIC33EVM-PDK board from Mouser.com and need all of
the Linux drivers for all of the chips on that board. This board appears
to be the same thing as the audio part of my FlexRadio Flex 1500 amateur
radio. I haven't been able to use the radio yet because my netbook
computer cuts off the last few lines of the display. I think I can get
it to work with Wine and set the display so I get all of the lines on
the screen. I know there are several others who would like to see a
Linux version for this radio, but FlexRadio.com only supports Microsoft
Windows. I know their new machines (6000 series) are using arm
processors (Davinci) and Linux, but are still in the process of being
built. Thanks again for your support.
