I use the Android Subsonic streaming player (I love subsonic and want to port my own from Maemo to native Sailfish once I get some time).

If I play one mp3 in subsonic (that means under android) it sounds just awful, garbled, like extreme low quality or something (doesn't matter if I open it in ES file explorer and play under ES Media Player). If I play the very same one under the native media player the audio clip sounds just fine. Note: It is not a streaming issue, it is fully cached.

There is a report here: https://together.jolla.com/question/76902/bad-sound-in-android-apps/ (but that one is closed for some reason, it is still a bug). It is mentioned in Vaarainjärvi as a "Known issue", but that is not really a separate bug report. https://together.jolla.com/question/71741/release-notes-software-version-11127-vaarainjarvi/#71741-known-issues

This MAY be related to specific bit rates or compression ratios. I don't experience as bad sound on all clips, so it may be related to specific compression or frequency properties of the audio file.

Some media info:

Format: MPEG Audio

File size: 13.6 MiB

Channel(s): 2 channels

Bit rate mode: Constant

Overall bit rate: 320 Kbps

Sampling rate: 44.1 Khz

Compression mode: Lossy

Writing library: LAME3.99r

Encoding settings: -m j -V 4 -q 3 -lowpass 20.5

NOTE: I can provide a short clip if that is needed by the sailors.

I'd be interested to know if this quality loss is similar to the bug in recorded audio: https://together.jolla.com/question/17528/sound-quality-of-video-recordings/

simo: It doesn't seem like it though, I mean this is only under the Android Alien Dalvik I experience this and only for certain clips (it may be there for all clips, but only very noticable on higher sample rates). And your link seem to be related to recording, not playing, right?

But how knows, it may be in same problem area. Maybe pulseaudio is involved in this somehow.

Yes, the other bug is affecting only recording. I was secretly hoping these might be somehow related (via pulseaudio for example), but if the sound is different, definitely not then :(
