On a Debian testing box w/1.1.0.13 and 2.6.11 kernel (w/ALSA) things are working quite well except that the touchtone sounds are not working. Using echo123 I found that they are being generated but so faintly that menu systems do not recognize them. I've fiddled everything I can find in the mixer but nothing seems to affect the volume of these tones.
FWIW, sound card is:
0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
with all the various snd_* modules loaded (including OSS emulation).
Anyone else have issues with touchtone sounds? I find nothing in the Knowledgebase about this, except that it's supposed to work... I've got no response so far to my support ticket.
Cheers,
