Mě třeba DOSBOX běhá parádně na 12.04. Dal bych mu šanci, pochybuju, že tu někdo používá DOSEMU. A nebo Googlit : 9.3. Why doesn't my soundcard software work with dosemu?
Dosemu includes a Sound Blaster 16 emulator called SBemu. See sound-usage.txt for information on setting this up. It may not work for everything. Programs that are known to work are Impulse Tracker and most games. One that is known not to work well is FastTracker II.
If you have trouble getting sound to work at all, make sure you have a working OSS driver and have configured everything properly as described in sound-usage.txt. If most of your sound software works but some programs don't detect sound, make sure your BLASTER environment variable is set properly. Finally, make sure you are aware of the difference between digital sound, FM, and MIDI; it may be, for example, that you have digital sound working but MIDI isn't set up properly.
If you believe DOSEMU really is having trouble with a specific program, and it isn't a configuration error on your part, then please, submit a bug report! Have a look at sound-usage.txt for information on getting debugging output.
