Oh, this is really amazing news with the 16MB PSRAM. I got a bit further with the SD card streaming. Using PSRAM helped quite a bit to make it more stable, but as soon as I go a bit crazier with the step sequencer and notes, I start getting issues. I think loading all the samples into PSRAM...

Haha funny, that's literally what I was about to ask. I already have the PSRAM sitting in front of me, but I haven’t soldered it yet. Probably my next step. I was basically just doing some research on whether it makes more sense to use two PSRAM chips (16 MB total) versus one PSRAM and one flash...

Haha yep, asking AI actually led me to cut a PCB trace so I could move the CS pin 10 that my display was using to another pin, because apparently the internal SD card was using that SPI pin. After doing some digging though, I also found out that the SD card slot is actually using SDIO. Sorry, I...

I think there was a similar thread a while ago. Basically, I'm having an issue where streaming samples from the internal Teensy 4.1 SD card reader causes audio stuttering or other glitches as soon as there are updates on my SPI display. So far I've been able to minimize it by only updating the...

I modified my pcb as you described and got the resistor working, also I finally got some sound out of it, but it's still far from ideal. It's hitting the correct frequency and a sine wave sounds good, but everything else, like square or sawtooth waves, sounds broken. I feel like experimenting...

Thanks a lot, both of you. That's all very helpful and gives me hope again. 🙂 It would have been a miracle if it had worked straight away, but I would love to make sure my second version is definitely working. :)) But yeah, it looks like the only thing left is to get the resistor for MCLK onto...

Thanks a lot for this thread. I am already happy that it should work :) I had a brief look through it, and the only thing I noticed is that there seem to be 100 Ω resistors on BCLK, MCLK, and WCLK. Are those really so important that I wouldn't be able to get the audio codec working without...

Hi. I made a custom pcb with a presoldered TLV320AIC3104 but I can`t get any sound out of it and I don`t know what is wrong. Its probably a bit messy, but thats how I have it connected. Also for DVDD I made sure it gets 1.8V. I had to fix that manually later on. my teensy connection...
