[SOLVED] files with samplerate 48.0 kHz play slow

[agent_kith]

Hi!

I'm still loving Snakeoil-OS, in fact, I'm back after a couple of weeks of trying out wtfplay, which I thought sounded better than Snakeoil until I came back just now!  Anyway, that's not why I'm writing here. I'm writing here because I couldn't figure out how to use the bug tracking system yet...

I just installed the 1.0.11 firmware, and re-tested a strange behavior I first noticed in 1.0.10, although it could have been there before.  When I play mp3 or FLAC files which have a 48 kHz sampling rate, they sound noticeably slower than expected, quite likely 44.1/48 (91.9%) as fast.  It sounds cool, like all the singers are huffing nitrous oxide, but it's probably not intended behavior for the player. It may be interesting to add that files with 88.2, 96 and 192 kHz sampling rates play perfectly.

It's easy to find 48 kHz files with the advanced search in LMS.  Just choose samplerate equals 48.0 kHz and click the Search button.  If you don't have any files encoded at that rate, I can email you some.

Thanks again for making such a great music player!

What audio device are you using again?

This is usually the case when the audio card is 'rate locked'. I do own an old SB16 card where it's S/PDIF output can only do 48 kHz and it's multiples (resulting in a higher pitch). And looks like yours is the opposite - rate locked to 44.1 kHz.

Can you SSH into your computer, and run

Code:

sudo alsamixer

screen cap the picture of all the outputs? Hopefully there is an option to unlock the rate lock. Also check the music player menu, when playing music, what rate is it displaying? (You need to hit the refresh button to retreive the lasted audio stats).
