As others have noted, the game had no audio on initial launch. The steps I needed to follow to get audio were as follows:

1. Edit the winetricks script (possibly as root) to ignore quartz installation by searching for load_directmusic() and commenting out w_call_quartz below it.

• # {nano|vim|whatever} $(which winetricks)

2. Install directmusic through the edited winetricks script in the Recettear prefix

• env WINEPREFIX={{steam library path}}/steamapps/compatdata/70400/pfx winetricks directmusic

3. Launch winetricks and set the sound=alsa option in the Change Settings menu
4. Launch winecfg for that prefix and set the dsound library override to native

After that, the game worked fine- no crashes, no visual glitches or audio skipping for 2 hours of straight gameplay.

Previously described workaround fixed the audio issues
