My HiFiBerry stops playing sound after it runs a couple of hours. The LED D2 is on (green), the LED D1 is off. The DAC is still recognized by alsamixer. But when I play any sounds, the system does actually play it, but I don't hear any sound. A reboot of the raspberry helps and the sound is working again - for a few hours.
Any ideas, how I could further debug this issue? What could I check?
As a reboot fixes this, this sounds like a software problem. What software are you usng?
Best regards,
Daniel
Thank you for your response! Yes, that sounds reasonable. The problem occours, while I run my own python software. But when it happens and I try to play a sound via aplay or similar, it doesn't output any sound as well? Does this mean, that my software crashes the driver or something and a reboot fixes that? Is there any log around, where I could have a look?
What does the off-state of the D1 LED mean? I noticed, that both LEDs are on (green) as long as everything is working.
Thanks again!
D1 off means that playback has been stopped. I know about a memory leak in very old Linux kernels (at least 2 years old). If you software crashed the kernel driver, you might check the output of dmesg if you can find some problems there.
It is also possible that your software does not send data fast enough. If this happens, the driver might hang waiting for new data.
Best regards,
