5 I'm using kernel 2.6.5 with alsa, my sound module is snd-intel8x0. When I ran
6 fgfs, I'd get quite 'choppy' sound (wasn't smooth, there'd be a couple of
7 breaks in the sound every second or so). Running arts, and starting fgfs with
8 "artsdsp fgfs" (from the artsdsp website: "When an application is run under
9 artsdsp all accesses to the /dev/dsp audio device are intercepted and mapped
10 into aRts API calls. While the device emulation is not perfect, most
11 applications work this way, albeit with some degradation in performance and
12 latency.") would improve the situation, but it seemed to still be choppy.
15 echo "fgfs 0 0 direct" >/proc/asound/card0/pcm0p/oss
17 (from the alsa kernel OSS emulation website:
18 "The direct option is used, as mentioned above, to bypass the automatic
19 conversion and useful for MMAP-applications")
21 made my sound work beautifully when fgfs was run with artsdsp. Running without
22 artsdsp however (with artsd suspended or killed), would give me no sound at all
23 (which I find a bit strange)
