Hi all,
I've just installed KnoppMyth. However I cannot get audio from the WinTV card output by mythfrontend. If I connect a cable from the tv card to the sound card, then I get straight audio from the tuner.

But I need to be able to get the audio setup properly. Can someone help out?

Here's my current configuration:

0000:00:0f.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
0000:00:0f.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
0000:00:12.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 08)
0000:01:00.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX 440 AGP 8x] (rev a2)

I have the following modules for sound:
# lsmod|grep bt
snd_bt87x 11976 1
snd_pcm 81156 3 snd_pcm_oss,snd_bt87x,snd_ens1371
snd_page_alloc 9352 2 snd_bt87x,snd_pcm
snd 47332 13 snd_pcm_oss,snd_bt87x,snd_mixer_oss,snd_ens1371,snd_rawmidi,snd_seq_device,snd_pcm,snd_timer,snd_ac97_codec
bttv 174316 2
video_buf 18692 1 bttv
firmware_class 9472 1 bttv
i2c_algo_bit 10632 1 bttv
v4l2_common 6912 1 bttv
btcx_risc 5896 1 bttv
i2c_core 20736 4 tuner,tvaudio,bttv,i2c_algo_bit
videodev 9344 3 bttv

I've tried using both /dev/dsp0 and /dev/dsp1 in mythbackend, with different results, neither of which have produced sound. If I use /dev/dsp1 (which I thought to be correct given I'm using snd_bt87x) I'll see this in mythbackend:

2005-03-31 22:10:47.876 NVR: Only read -1 bytes of 4096 bytes from '/dev/dsp1
read audio: Input/output error

If I use /dev/dsp0, then what I get is a lot of static on the sound, starting at a low volume and increasing volume. I'm also thinking that /dev/dsp0 is the same as the OUTPUT device, not the input, correct?

Sound in general works fine, like if I play something with xmms, or if I connect the audio out from the tv card into the audio in for the sound card.

Any help is greatly appreciated!
Thanks
