The behaviour when opening /dev/dsp read-write changed. It now enables
full-duplex (16-bit input, 8-bit output), so Quake2 is writing 16-bit
samples to a device which assumes 8-bit samples.
Try the following patch:

sb_dsp_reset(devc);
/* The ALS007 seems to require that the DSP be removed from the output */
