Configuring my SA9227 with PCM5102A 32BIT / 384KHZ USB3 Hifi Audio DAC on Linux

Configuring my SA9227 with PCM5102A 32BIT / 384KHZ USB3 Hifi Audio DAC on Linux

SA9227 with PCM5102A 32BIT / 384KHZ USB3 Hifi Audio DAC 

I was looking for a high end Audio DAC for Linux and found this unit. I wanted to generate IQ moderation for a transmitter and this module would work nicely. It Unfortunately it only works on USB3 so this one cant be used on raspberry Pi 3 :-( but works fine on my Ubuntu laptop.

Description

• Input :5 V (USB supply),
• THD+N: <0.005% (RL = 10 kω)
• independence: >95 dB
• DRC: >95 dB
• USB sample rate:16-32BIT/32-284KHZ

I first tried it on a USB 2 port but got this error when connecting the Device to the usb2 port

/var/log$ tail -f syslog

I then tried it on a usb 3 port  and got the following log.

This looked promising

I then checked if Alsa would see the device

sudo aplay -l

and the yellow was added as a new device to be used.

I could now use the normal Alsa audio controls with this device.

Ethernet network interface not detected in Ubuntu 12.04

Ethernet interface eth0 not detected in Ubuntu 12.04

I got a new I7 ASUS motherboard P8H77-V (3 PCI Slots for sound cards) and Ubuntu 12.04  64Bit and 32bit versions did not detect the motherboard default Ethernet port.

Check that the led's flicker when you plugin the Ethernet cable, if not check in your bios and enable Ethernet there.

Here is what I had to do to make it work.
Run the following command in your terminal.

sudo  lspci
You should see the following in the list of devices to confirm this is the Ethernet interface you have.

 Ethernet controller: Atheros Communications Inc. AR8161 Gigabit Ethernet (rev 10)

Then install the driver from Ubuntu

Don't get the drivers released after 2012-05-10 it will not work

 wget -O- http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-05-09-p.tar.bz2 | tar -xj

cd compat-wireless-2012-05-09-p

./scripts/driver-select alx

make

sudo Make install

Then load the new driver module.

sudo modprobe alx 

If your network cable is connected with your router on DHCP.

run ifconfig and you should see your interface eth0

ifconfig to see your new ethernet ports.

and it should work now.
