Native Alsa Support

I have just installed mythtv under gentoo (kernel 2.6 with build-in alsa
support) compiled with Native Alsa Support. When I try to play a
program from mythfrontend I get:

Error opening audio device (/dev/dsp). No such device

I believe /dev/dsp is an OSS device and since I compiled with native
alsa support, I would expect this. My question is:

What do I use in the General/Setup/Audio section?

I am not presented with any choices for audio device except OSS
devices. I am using devfs and I do not see how to configure the
frontend to use a devfs native alsa device.

Can anyone advise me on this?

Thanks,
Dick

Yes, that is the OSS device.

ALSA:... Where ... is the device. In my case I use ALSA:spdif to use the
optical SPDIF output on my motherboard. The ALSA must be uppercase.

Yes, search the archives. This has been covered many times.

In mythfrontend Setup menu General/Setup/Audio...

I am given is a list of choices:

/dev/dsp
/dev/dsp0
/dev/dsp1
/dev/dsp2
/dev/dsp3
/dev/adsp
/dev/adsp0
/dev/adsp1
/dev/adsp2
/dev/adsp3

ALSA:SPDIF is not among them. Where do I specify alsa:spdif?

Thanks for your quick reply.

I looked there before I posted and again just now but I am unable to
find an answer to my question above.

UPDATE!

I discovedred that the "audio output device:" field allows one to type
in it (rather than just picking from the available options).

Who knew?

So I entered: ALSA:default and it worked.

Thanks again,
Dick
