No sound in Linux?

[Nostromo]

I can't get dom3 to output sound in Linux. Note that the rest of the system (e.g., mplayer etc.) does work with sound.

Environment: Gentoo Linux, Kernel 2.6.17.7, KDE 3.5.5, ALSA 1.0.13, arts from KDE 3.5.5

1) dom3 default sound via arts: Crash

Code:

---

(/local/opt/dominions3) 506 % ./dom3

*** glibc detected *** ./dom3: free(): invalid pointer: 0x0be346d8 ***

2) dom3 sound via legacy OSS: ALSA error

Any ideas on how to fix this would be appreciated ...

For ALSA it looks like a bug in the oss emulation. Usually you can run oss programs with alsa without using aoss (which is the probable cause of that bug), but I don't know how it's is with gentoo. Running "./dom3 -o" with alsa works fine for me.

Does artsd run ok with other applications? It looks like it crashed.

Thanks for the hints, I did some more testing:

1) Running ``./dom3 -o'' without aoss does work (after a fashion): My machine has two soundcards, and it was outputting to the wrong (unconnected) one. I'll now try to figure out how to redirect OSS output to the correct card.

2) As for arts: artsd is definitely running and working fine. For example, here are a few lines of output from mplayer:

Code:

Only the client (dom3) crashes.
