Hi @0x0fe , thanks for your question. I am a Bluetooth guy and I will check the Bluetooth stack for you first.
I would like to ask some questions on how to reproduce the issue, so that I can perform some local tests:
Hello, thank you for the return. For testing we used this implementation https://github.com/pschatzmann/ESP32-A2DP which is a direct port of the IDF example for A2DP sink. Yes it has been tested with PSRAM enabled and disabled, via the menu in arduino since the firmware was generated here. By the way, we tested on D0WD too, with external PSRAM (a wrover module) and it works fine, so the problem really only occurs on D0WDR2. IT does not occur on D0WD nor D0WDQ6.
For the firmware, i suggest you try with the same configuration we used, I can provide ready made binaries if you want, If you use a different DAC let me know the I2S mode. On our side for production we use ES7148 and for tests we used MAX98357A. In both case the pinmap is as follow.
#define MCK 3
#define WS 5
#define BCK 18
#define DAT 21
#define MUTE 4
Also relevant : here are the I2S DMA buffer size/count and A2DP buffer size/count used for these tests (we tried with different sizes too and it did not change anything).
#define I2S_BUFFER_COUNT 20
#define I2S_BUFFER_SIZE 512
#define A2DP_BUFFER_COUNT 30
#define A2DP_BUFFER_SIZE 512
So, PH stands for Philips and RJ for Righ Justifed, which are the I2S formats for ES1748 and MAX98357A, respectively.

These are 4MB (32Mbit) Flash full dumps and thus are intended to be flashed at address 0.

Hi @0x0fe thanks for the information. I will try to perform some test locally. According to my information, there are some espressif customers that used D0WDR2 in their audio application products.
By the way, how many pieces of D0WDR2 chips have you tested, did they all have this issue and make no differences?
Hi @wmy-espressif We have tested several units, so it is not a problem with one units, all D0WDR2 chips we tested shown the same problem, also, as mentioned, it is not structly an I2S problem because when we play audio from other sources, such as SD_MMC there is no problem, the audio is not stuttering. So it only occurs with the A2DP.
Hi @0x0fe ,
Sorry, I don't know how to run your project. Can you test it in the following way?
#include "BluetoothA2DPSink.h"
BluetoothA2DPSink a2dp_sink;
void setup() {
static i2s_config_t i2s_config = {
.mode = (i2s_mode_t) (I2S_MODE_MASTER | I2S_MODE_TX),
.sample_rate = 44100, // updated automatically by A2DP
.bits_per_sample = (i2s_bits_per_sample_t)32,
.channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT,
.communication_format = (i2s_comm_format_t) (I2S_COMM_FORMAT_STAND_I2S),
.intr_alloc_flags = 0, // default interrupt priority
.dma_buf_count = 8,
.dma_buf_len = 64,
.use_apll = true,
.tx_desc_auto_clear = true // avoiding noise in case of data unavailability
};
i2s_pin_config_t my_pin_config = {
.bck_io_num = 26,
.ws_io_num = 22,
.data_out_num = 25,
.data_in_num = I2S_PIN_NO_CHANGE
};
a2dp_sink.set_pin_config(my_pin_config);
a2dp_sink.set_i2s_config(i2s_config);
a2dp_sink.start("MyMusic");
}
void loop() {
// disable watchdog
}
Thanks
ok, let me test
so, i tested, same problem

}

}
actually, it is even worst. D0WDR2 stuttering.zip I tried from iphone (13 last IOS) and from PC (win10) and i notice that on iphone it cuts completely at regular interval of varying length (silent), on PC it doesnt cut, but in both case the stuttering is as bad as it can be.
please note, we use 16bit as our DAC only supports 16 and 24 bit, not 32. Also, pin mapping is different than your code, you may want to adjust your test platform to match ours, in case this isue has anything to do with the pin mapping.
Hi @0x0fe ,
BaseType_t rc = xRingbufferSend(s_ringbuf_i2s, (void *)data, size, (portTickType)0);
b. i2s_ringbuffer_size may be too small.BTW, I hope you can provide a test log after the test.
Thanks
Hi @xiongweichao 1) we have tested with android too, actually on some old android even the D0WD, but on newer android and on IOS / PC it is working fine. On D0WDR2 it is failing with all platform, old android, new Android, new IOS, and PC (win10).
2 a) i am not sure what the suggestion is here, do you want me to verify wether this call is blocking inside A2DP sink queue?
2 b) as mentioned previously, we have already tested with various size and number of buffers for I2S (and for A2DP too), last time i tested with 8 buffer of 512 byte on the I2S and it was still stuttering a lot. For the sake of it i will test again.
3) ok, i will see how we can enable this log in the arduino core, hopefully this is possible with a flag, otherwise i would have to move the testing code to IDF, which will take time.
@xiongweichao Okay i will run the test in IDF, can you clarify how to enable MCLK on this specific example, because the DAC i use for test here do need MCLK on GPIO3. Do i jsut need to add it to the I2S pin config structure here?
@0x0fe The use of I2S is exactly the same as that of arduino, you can directly add it.
so, i decided to give a try to IDF 5.0.1, and i can confirm the problem is still here, however enabling the bluetooth logs indeed shows a lot of buffering undeflow issues .
so, here i disabled the color formatting for better clarify, i also enabled the BT driver to use external PSRAM first and allowed dynamic memory allocation, just for test, and i can say the result is even worst because it now also saturates the PA and the volume control is inoperant, that is, i can set it to 5% and it shows in the log, but the actual output on the DAC stays at maximum (and beyond). Not sure how this relates to external PSRAM and memory management, which are the only tparameters i modified, but this overloading and lost of volume control did not occur before.

So, i think i found a big clue, if i change the GPIOs assigned to I2S to those used by default (22,25,26), the problem instantly disappears. No more underruns. Of course i cannot check the audio, because i use our actual hardware and thee is not easy or convenient way to strap/route these GPIos to the DAC, but anyway i am quite sure there would be no stuttering. So now the questions are :
-why and how would the I2S GPIos have an impact on the buffer underruns / BT performance / PER. -how comes this is not the case on D0WD and D0WDQ6? -which mitigation?

after more test, i can be even more specific : this problem is caused by using GPIO21 for DATA, as soon as i change DATA gpio to something else, for example GPIO19, the problem of underrun disappear.
so, it is a little more complicated apparently, not only GPIO21 cause the issue, in fact many combination of GPIOs cause these underruns, I have tested the last pinmap and the audio is perfect. One problem remains though, the volume control is inoperant, it shows up in the log, but has no impact on the level out of the DAC.
so, to be more precise about the problem with audio control, 1) the volume change notificatiosn are working, in both directions but it does not affect eh audio level. 2) there is an horrible clipping going on, never got this clipping before and it is not coming from the PA since we use class A. This really sounds like a digital clipping.

[Uploading D0WDR2 A2DP clipping.zip…]()
i juste ran the ad2p library test (so, with IDF 4.4) ,
1) there is no clipping and no stuttering, everything is smooth when using GPIO19 for DOUT.
2) level is lower than IDF 5.0.1 A2DP sink example (using identical source) so it seems IDF 5.0.1 is indeed overdriving the I2S datas somehow, to the point of feeding clipped datas to the DAC.
3) the volume control works fine on the A2DP library running over IDF 4.4 so it seems this problem also relates to IDF 5.0.1.
So, it confirm the root cause of the problem is related to pin muxing or "cross bar" or maybe some other issues tightly related to the pin mapping. As far as we are concerned we will jsut use GPIO19 instead of GPIO21 to go around the issue since we already wasted a lot of time on this, but it is certainly worth investigating what causes this issue, because again it oes not occur on D0WD nor D0WDQ6, and it seriously affects the usability of I2S whenever A2DP will be used, in effect many pin conbinations will not work at all.
@0x0fe May I ask if this problem still exists in the latest idf v5.0?
Answers checklist.
General issue report
So the context is a consumer product design which uses an external DAC (ES7148) and provides audio playback via different sources, MMC, wifi and bluetooth (A2DP), initial tests were conducted on ESP32D0WDQ6 and everything worked fine, the A2DP is smooth, no stuttering or anything. The A2DP firmware is based on ESP-IDF v4.4.4.
For final implementation we switched to D0WDR2 since we use both wifi and bluetooth and a relatively large application logic, additional PSRAM is required.
Sadly we found that the D0WDR2 cannot work normally for the A2DP, there is a massive stuttering, and the playback is totally abnormal. There is no playback issue when playing audio from MMC.
In order to confirm the problem we performed multiple test, at first changing compile time options such as Flash speed (40M and 80M) CPU speed (160M and 240M) PSRAM enabled/disabled, and even buffer sizes for I2S and A2DP, we found no difference at all, in all cases the stuttering was still present with the same magnitude on the D0WDR2 and no stuttering at all on D0WDQ6.
Then we decided to make comparative tests with devkit instead of the product hardware, we changed the DAC for one without master clock (MCLK) as i suspected it could be related to MCLK, so we used : -one devkit with D0WDQ6 + MAX98357A -one devkit with D0WDR2 + MAX98357A Identical pinmap, and identical firmware binary flashed in both.
We tested the same way, with an iphone as source and running a simple A2DP firmware (also tried different source such as PC): -D0WDQ6 : perfectly smooth, no stuttering at all -D0WDR2 : massive stuttering all over, unusable
With the log in verbose mode, there is absolutely no error or warning of any kind, both output exactly the same thing. So the problem lies somewhere deep and is not a simple buffer underrun or something (well unless it doesnt gets catched).
Sadly, we can now confirm the problem comes from the D0WDR2 chip itself and not the hardware, the DAC or the firmware. I have no idea yet of what causes this, nor what exactly changed in the die between D0WDQ6 and D0WDR2, both are rev 3 so i would have expected the D0WDR2 just be a D0WDQ6 with a PSRAM attached, but apparently it is not the case ,I2S block? bluetooth stack? who knows.
So please espressif have a look at that. Attached is a quick audio recording of the problem (from an iphone).
