console output not sync'ed to the sound when running with ALSA #31

Closed ruby-R53 closed 4 months ago

ruby-R53 commented 5 months ago

when compiling sidplayfp with ALSA support only, the verbose output (-v2's notes, control registers, and more) is updated really fast, not following what's currently being played. the time count seems to be only a tiny bit faster than normal though

i pulled the latest version from here, but i remember this also happening when installing from the gentoo repositories without the pulseaudio USE flag a while ago

No problem here with ALSA. Can you please try again with the latest change? (https://github.com/libsidplayfp/sidplayfp/commit/2bf29448052c1fe067f8a81681038b8a4d518782)

that's weird, now the output runs really fast until it hits the 12-second mark, then it continues at the normal speed, while the song plays at normal speed the whole time so it doesn't get sync'ed here neither

I've been able to reproduce this by setting the frequency to 8000, it skips first couple of seconds then plays normally. Guess this is the same as #20

ruby-R53 commented 4 months ago

hmm, as i lower the sample rate the skipping goes further

i had it set to 192 kHz, now i set to 96 and it skips the first 27 seconds, then when setting to 48 it skips the first 54 seconds, and so on

Is this the same issue as #20 ?

ruby-R53 commented 4 months ago

yeah, seems like it

drfiemost commented 4 months ago

Ok, let's continue the discussion over at #20
