get second play of the time buffer

[azegami]

Excuse me
I want get second play of the time buffer
I wrote this code.

float offset;
alGetSourcef(source, AL_SEC_OFFSET, &offset);
return offset;

But, I was not able to do so.
I was able to get in this code.

float offset;
alGetSourcef(source, AL_BYTE_OFFSET, &offset);

ALint bufferID, frequency, bitsPerSample, channels;
alGetSourcei(source, AL_BUFFER, &bufferID);
alGetBufferi(bufferID, AL_FREQUENCY, &frequency);
alGetBufferi(bufferID, AL_CHANNELS, &channels);
alGetBufferi(bufferID, AL_BITS, &bitsPerSample);

return ((double)offset)/(frequency_channels_(bitsPerSample/8));
Why do could not be?
I would appreciate your favor.

Hey. I was making my game engine and searching for how to fix a problem when I found your question. I know it is old bu I know how to fix it. You also helped me. AL_BYTE_OFFSET was new for me and I was able to set the playback point. Switch alGetSourcef to alGetSourcei and verify the formula to seconds

(float)(bytes * 8 / (channels * bits)) / (float)frequency

bytes is alGetBufferi(m_buffer, AL_SIZE, &bytes);
