Hi Gunter, I think this problem started happening when I upgraded from Debian Wheezy to Debian Jessie. If nothing looks amiss in my code, it probably is a sound driver problem. But since it works 100% of the time in ogg123, I feel I must have missed some corner case. My audio driver is almost always active. I usually have my music player going in the background when I do my testing. The problem

...gured it out. What I needed to do was fill the buffer with more data before handing it off to ao_play. It requires lots of bookkeeping, pointer arithmetic, and a sufficiently large buffer. First, the bigger buffer. I just pulled this code from ogg123: #define PRIMAGIC (2*2*2*2*3*3*3*5*7) #define AUDIO_CHUNK_SIZE ((16384 + PRIMAGIC - 1)/ PRIMAGIC * PRIMAGIC) char convbuffer[AUDIO_CHUNK_SIZE]; const int convsize = AUDIO_CHUNK_SIZE; The loop is now more convoluted. Here's the old one, for reference: long bytes_read = 0; do { bytes_read = decode_vorbisfile(&vf); ao_play(device, pcmout, bytes_...
