amixer output

When booting from the talkingarch CD, the following modules load automatically (as reported by lsmod | grep snd).

snd_hda_codec_idt      55648  1 
snd_hda_codec_hdmi     24487  1 
snd_hda_intel          26180  1 
snd_hda_codec          98033  3 snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_intel
snd_hwdep               6300  1 snd_hda_codec
snd_pcm                75167  3 snd_hda_codec_hdmi,snd_hda_codec,snd_hda_intel
snd_page_alloc          7217  2 snd_pcm,snd_hda_intel
snd_timer              18934  1 snd_pcm
snd                    59989  7 snd_hwdep,snd_timer,snd_hda_codec_hdmi,snd_hda_codec_idt,snd_pcm,snd_hda_codec,snd_hda_intel
soundcore               5442  1 snd


When booting the CD with the command:

arch64 brltty=auto,ttyUSB0,en_US modprobe.blacklist=snd_hda_codec_hdmi

the hdmi module no longer shows up under lsmod, but I still don't have sound.

"aplay -l" reports the same information for card 1, but there is no card 0 entry.  

The archwiki has tips for redefining default soundcard, but it looks like they require re-booting the kernel.
