Fatdogarm for Raspberry pi3 - headless
Good news! I was able to solve my problems with sound.
Here is what I did.
1. I dragged in all of woodenshoe-wi files that he gave me
2. Then I dragged in the bcm2709 and bcm2710 files from the latest berryboot image.
This overwrote the files of woodenshoe-wi (Not sure if this is needed????)
3. To get latest wireless driver for raspberry pi3 I opened the
berryboot package and extracted 'shared.tgz'
I put the firmware and modules i found there in /lib
4. In config.txt I wrote 'hdmi_safe=1' and audio is on .
5. I used a fat32 SD card as usual and booted up the raspberry pi3.
I got a strange warning that the video mode wasn't compatible.
Yet it did boot up . And best of all the audio works well and the computer is
significantly faster that raspberry pi2.

See First Post for zip package
I put together a zip package so others can enjoy.
It should work for all raspberry pi3 boards ... but I only tested with
my brandnew model B+ which I highly recommend
I added ptm Timer 2.5 to set a reminder and put faq documents in /root so users can
read how to make fatdog packages and set up WIFI
Tip: put mp3 files in /Music folder if you want music to play at first boot.
Also you will have to learn to set the clock.

Glad you got your audio working!
You mean the .dtb files? Was it needed? I don't have a Pi3+ to test and it looks like the 3+ uses a different .dtb than the 3.2. Then I dragged in the bcm2709 and bcm2710 files from the latest berryboot image.

You mean the audio problems had something to do with the hdmi_safe setting?4. In config.txt I wrote 'hdmi_safe=1' and audio is on .

"Ouch"... Even with the exchange rate, that's a bit pricey... :-/don570 wrote:I bought a raspberry pi 3 $70 +10 tax CAN
I paid $35 US for mine (and see that they're dropped the price further)

hdmi_safe=1 at first boot
The same results as:
hdmi_force_hotplug=1
config_hdmi_boost=4
hdmi_group=2
hdmi_mode=4
disable_overscan=0
'config_hdmi_boost boosts' the voltage level to my TV monitor. This appears
to help.

I took 4 files from berryboot package ...

bcm2710-rpi-cm3.dtb
I'll put back the woodenshoe-wi files and test.

New version available on first post.
fatdogarm-pi3-06-14-2018
Changes:
1) OGG format files can now be placed in /Music folder.
I discovered that omxplayer.bin will play this format.
So I made this the default player for this format in playmusicrc file.
2) /usr/share/audio/ folder now contains sample files

Re - posted fatdogarm-pi3-06-14-2018.zip in first post.
I tested and everything is now OK.
___________________________________________
Note that I didn't use all the dtb files from berryboot.
I think that the woodenhouse and berryboot files are interchangeable.
Just to recap....

bcm2710-rpi-cm3.dtb
A bunch of others I left out.
If I left something out that is needed then you can report the problem.

Thanks Don. I need to give this a try, as soon as I can get back to playing with the Pi3+don570 wrote:Re - posted fatdogarm-pi3-06-14-2018.zip in first post.

A note for people using VNC server...
Just typing 'x11vnc' in terminal starts the server.
The port is 5900, the display is :0
Then with a PC running linux type ....
where 192.168.1.XXX is raspberry pi address.
Password is woofwoof
With a windows machine use XMING

It works well however it only records with a microphone.
If i try to record with regular stereo patch cord there is
horrible buzz problem.
alsamixer is good way to select driver.
I am using mhwaveedit to set the audio level. alsamixer and retrovol have settings.
I found that I can record with mhwaveedit if I set the format to
mono 44100 khz 16 bit.

To record a mp3 file is useful to reduce need for space.
To record 10 seconds of audio here is command I type...
or for better sound quality
Here is a good explanation of how to set up this USB card adaptor..

I am trying to record a radio program .
I discovered that due to impedance mismatch ---> the output headphone jack of a radio shouldn't be used.
The mismatch will cause the voltage to be too high which causes distortion.
The regular line output of a radio will work better. However,
a problem I have found with both of my raspberry pi boards -->
Hiss is produced that causes weak AM radio stations to not be listenable.
USB sound card is not the problem, rather it is the raspberry board that
is causing the interference.

Yes, folks have got away with using the headphone socket for too long. Big problem when a proper audio-out socket is omitted, a frequent feature on newer TVs.I am trying to record a radio program .

The mismatch will cause the voltage to be too high which causes distortion.
Of course, a balun impedance-matching transformer is required by serious recorderists. They used to be costly and bulky, but now cheaper if a little less available.

to the microphone input of the external USB sound card.
Normally you don't have problems with the line-in of regular sound cards.
My Sony receiver has a special line input port for portable mp3 players like Apple ipod.
Sony says that it adjusts level of the audio better than the other line-in ports.
