Hi, I have configured the I2S as it is shown in this topic and the I2S Output work perfectly. Now, I'm testing the I2S Input and I've found some problems. I'm trying a loopback between I2S_DOUT and I2S_DIN to test the I2S input. When I try to use the arecord command there is an error: arecord: main:828: audio open error: No such file or directory Could you indicate how did you test the I2S input? Thank you PD: here are the output of the arecord -l and arecord -L: root@OpenWrt:/# arecord -l **** List of CAPTURE Hardware Devices **** card 0: AudioI2S [Audio-I2S], device 1: ralink-i2s-dir-hifi dir-hifi-1 [ralink-i2s-dir-hifi dir-hifi-1] Subdevices: 1/1 Subdevice #0: subdevice #0 root@OpenWrt:/# arecord -L null Discard all samples (playback) or generate zero samples (capture)

Hi @Ian-Steele, Sorry that you did not come right. I've compiled a build for you tonight based on repo as of today. Ive added in generic support for I2S playback and record (version 0.3.2 b233). I2S_Audio_Build Let me know how it goes. Cheers, UFD

OpenWRT has a driver for the Raspberry Pi Audio Injector soundcard that uses the WM8731, however, it utilizes the Raspberry Pi's Broadcom I2S and I2C driver. Starting at line 297, you can see it here. So, the goal here should be, at least for the software side, is utilize the ralink-i2s driver (I believe it's called that) and the Omega's i2c driver in the Audio Injector driver and build it for the mt76x8. On the hardware side is to adapt the pins to connect the spi, i2s, and i2c lines to the Omega2. Onion team, have the i2c and i2s audio issues been fixed in the latest firmware?
