Recording hang and cannot record even one file in odroidN2+ due to recordCallback function was not triggered and Uninitialised value was created by a stack allocation

Charxil commented 6 months ago

Hello, I am using scarlette audio interface and odroidN2+ which is aarch64 architecture to record the acoustic data every 10 mintues 24/7. However, the script hang after recorded 4 minutes for the first acoustic file without providing any error message. When I use valgrind to troubleshoot, it mentioned error was related to Pa_Initialize(), libasound.so.2.0.0. Please refer to below valgrind output. Moreover, when I did troubleshooting with the print statement, the script hanged at the end of the recordCallback function and the recordCallback function was not triggered anymore and the program hang. The same script when I run in odroidXU4, there is no such hang issue.

Therefore, I think the issue was related to libasound library or portaudio which is not compatible with the odroidN2+. Then I compiled the portaudio library inside the odroidN2+ but this does not solve the issue. My compilation procedure is as follows:

unzip the downloaded portaudio-master in odroidN2+ to folder /home/odroid/acoustic/portaudio-master/.
uninstall the libportaudio2 in odroidN2+ using below command: sudo apt-get remove libportaudio2
install libasound-dev using below command: sudo apt-get install libasound-dev
go to the folder /home/odroid/acoustic/portaudio-master
compile using below command: ./configure && make
copy the libportaudio.a to your main.c directory.

compile your main.c by delcaring the library path:

/usr/bin/gcc -pthread -fPIC -Wl,--gc-sections -L/usr/lib  -L/usr/lib -L../../../build/obj/gcc-linux-x86-64/debug obj/gcc-linux-x86-64/debug/main.o obj/gcc-linux-x86-64/debug/log.o   -lTw -lm -lconfig -lsndfile -lcurl -L/home/odroid/acoustic/portaudio-master/lib/.libs -lportaudio -Wl,-rpath,/home/odroid/acoustic/portaudio-master/lib/.libs

**Expected behavior**
The script should run 24/7 and generate an acoustic file for every 10 minutes.
**Actual behavior**
The script cannot record even one acoustic file. It hanged after recording 4 minutes and this duration is random when I rerun the compiled c program.

Inside the main function, the recordCallback was passed only once to  Pa_OpenStream. Pa_OpenStream is responsible for opening an audio stream. Once the stream is opened, portAudio library continuously captures audio data from the input device. Periodically, recordCallback() is called by PortAudio to save the acoustic file when it satisfy the conditon. 

Could you suggest how can I solve the hang issue since the recordCallback function was not triggered by portaudio? 

Thank you in advance.

Is this the same problem as #873?

Charxil commented 5 months ago

The recording hang issue scenario was the same but the error is different. Therefore, I created this post to get insights from experts.

Hello, I would like to follow up on this issue regarding the recording hang problem of recordCallback function is not triggered that I have been experiencing. I reached out since 3 weeks ago, any assistance or information you can provide would be greatly appreciated, as this matter is quite urgent for my ongoing work.

RossBencina commented 5 months ago

Looks like memory leaks in ibasound.so.2.0.0 (i.e. in ALSA code). My thoughts are:

could be an ALSA issue, no reason to think that it's a PortAudio issue
no reason to think memory leaks are related to the audio stopping

Quite possible there is an issue in ALSA or in PortAudio/ALSA, in either case we have no ALSA experts on our team at the moment, so we can only make suggestions when we have an idea. Right now we have no idea and no time to spend to help you. We are focused on finalising the PortAudio v19.8 release.

I do have an Odroid N2 here, and some availability for paid work, so if you have the budget you could pay me to help you debug it (understanding of course that I have little advantage over you debugging it yourself). If that is of interest please email me at rossb@audiomulch.com.

Recording hang and cannot record even one file in odroidN2+ due to recordCallback function was not triggered and Uninitialised value was created by a stack allocation #916
