Often, but not every time, when I start the game the sound is played at double speed. What's worse all other apps also start playing audio too fast, including paplay, Chrome etc. Even those which are started after I exit the game. This can be fixed by restarting PA or after killing all clients connections with paman (if there are none after I exit the game, sound seems to be working correctly). I believe no client should affect other clients like this, no matter how it's broken. A friend of mine completed Transistor without such issues using PA. I also found that something like this was long ago fixed in Wine but this game is native. At least more native than pure Win32 apps+Wine and it doesn't use Wine. It uses Mono though and FMOD as the sound engine. My soundcard is CA0106 Soundblaster (SB0410 SBLive! 24-bit), CPU is Intel Core i7-2600, 32Gb RAM, NVIDIA GeForce 770 GTX driver v340.65, Debian Jessie GNU/Linux amd64, Awesome WM 3.4.15, kernel v3.16. I also have another sound chip, ALC889 Analog. It's disabled in pavucontrol. You can also see some ALSA underruns, I couldn't fix it no matter what priorities and realtime priorities I set. They happen on both snd-hda- intel and snd-ca0106.

I also noticed that with s16le both Chrome and Transistor use "resample method: (null)" (according to pacmd list-sink- inputs), and with s32le it becomes "resample method: copy" for both. And no, Chrome isn't the culprit as it happens even when it's not running, I've tried. The speedup happens right after starting the game, I've run a song in Chrome and launched Transistor. First time it was ok in both Chrome and the game but on the second run the song immediately sped up to double speed. I have no idea how the sample spec (not the sample rate!) affects the speed but it's what it is. SBLive! seems not to support 44100 Hz as it switches to 48k by default and even if I set 44100 explicitly in the daemon.conf. Though here paman and pacmd disagree with each other, pacmd says "sample spec: s16le 2ch 48000Hz" and paman says "Default Sample Type: s16le 2ch 44100Hz". Mumble notification sounds doesn't crackle as they do on ALC889 @ 44100Hz so I believe pacmd is correct here.
