When the tests pass, the DS3 through DS6 LEDs will be solid. The other tests will run without requiring user input once the switch and button tests are finished. If this is not done within a minute of starting the test, it will timeout and fail.ġ1. In order to pass the test, all switches and buttons must be toggled on and off. LED DS3 should light up when switch S1 or button S6 are enabled). Note that the related LEDs should light up when the switches or buttons are in the on the state ( e.g. When prompted, toggle the switches (S1 through S4) and buttons (S6 through S9) on the board. Tests should start automatically and be shown on the Raspberry Pi display.ġ0. The board will boot into Linux to run the tests.ĩ. If two green LEDs are lit on the SOM without the blue FPGA LED being lit this means that the FPGA isn't getting configured properly which means there is an issue during early bring up such as the board's power sequence not running correctly.Ĩ. Confirm the green power LED and blue FPGA LED are both lit after a few seconds have passed (see the picture below). Make sure the power cable is plugged in and then power on the board.

Insert a jumper on the P9 header, between pin 1 & 2, to enable USB OTG mode.ħ. Plug the Ethernet loopback module into breakout board Ethernet connector (M1).Ħ. Plug the OTG adapter into the breakout board USB OTG port (P11).ĥ. Plug the micro USB on the UART port (P14) on the breakout board.Ĥ. Make sure all the switches (S1 through S4) are set to the off position.ģ. Insert the SDR2 SOM board with test suite SD card into the breakout board.Ģ. If they are not correct you will get a silent recording.1.

See the included help file for details on how to do this. Important note: Please make sure your mixer settings are correct before trying to record with SoundCheck. In this case the display Frame rate may need to be lowered. Also, not all PC's will have the speed to support a real time display when high sample rates are used.

While all Windows plug and play sound cards (Crystal, Yamaha, Creative sound blaster, ESS, etc.) are compatible, not all sound cards will support the full range of sample rates.

SoundCheck includes a built-in tone generator that allows test tones to be generated at a selected frequency and sampling rate. Stereo or mono sound can be recorded and played back at a variety of sample rates and resolutions. SoundCheck also provides an audio FX test and a surround sound test to analyse those advanced sound card features. Create perfectly formed test tones and loop them back into your sound card to look for distortion using PassMark audio loopback cables. Check the capability of your speakers to reproduce the highest and lowest frequencies (and your capability to hear these frequencies). Verify that your sound card can record and playback sounds at various audio sample rates.
