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

...a 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_read); } while (bytes_read > 0); Here's the new loop...

I've run into two problems with ogg123 that appears only when using the esound driver. Case 1: pops in output Audible pops, especially at low volume. Original mp3 file does not exhibit these pops, nor does oss output from ogg123, nor does esd output from mpg123. Things ruled out: disk speed - the HD is ATA/33 with DMA on. It's a single user
