[GRULIC] kiax cliente iax. problemas con el sonido

Hola lista,
paso a comentarles mi problema. quiero usar kiax para hablar por a
telefonos fijos, conectandome a voipcheap.
Eso lo hago bien. Lanzo el programa desde la consola, se conecta al
servidor y cuando intento hacer una llamada, me dice que hay problemas
con el sampleado y que no puede abrir el dispositivo de audio.
uso debian, tengo una pentium 3, mi placa de sonido es soundblaster
pci128. con lspsi me sale 00:08.0 Multimedia audio controller: Ensoniq
ES1371 [AudioPCI-97] (rev 07), no tengo problemas con el skype.. hablo
perfectamente... en la configuracion de skype veo como dispositivos de
audio, alsa y oss. en la configuracion del audio de kiax, veo /dev/dsp y
/dev/dsp1.
instale alsa, alsa-utils, alsa-oss. y algunas cosas que encontre en una
pagina.
desde ya les agradesco la ayuda..
saludos
juan
la salida en la consola es:
