 Posted: Tue Aug 01, 2006 8:49 pm Post subject: [SOLVED] ALSA hw:0,1 stopped working 'spdif' still does! |
 |
|
Hi all,
Up to fairly recently on my MythTv machine I could type the following and get sound through my spdif connection :
aplay -D hw:0,1 /usr/share/sounds/alsa/Rear_Right.wav
However that has stopped working, if I use '-D spdif' instead it works fine.
This wouldn't be a problem as in myth I can change the output to ALSA:spdif, however in MythMusic, since my recordings are not all 48000 Hz, this is no good. I was using a .asoundrc that did the rate conversions, but with hw:0,1 no longer working its not much use!
Any ideas?
Here's some system info :
| Code: |
alsa-driver et al = 1.0.11 (I've tried 1.0.12 to no avail)
|
| Code: |
stella ~ # aplay -l
**** List of PLAYBACK Hardware Devices ****

Note there's no mention of IEC958 on device 1 - could this be the problem?
Thanks, Bry.

Just in case anyone else has this problem, I have 'fixed' it. I needed to set 'IEC958 Playback AC97-SPSA' from 3 to 0. Thus :
| Code: |
mythtv@stella ~ $ amixer get 'IEC958 Playback AC97-SPSA'
Simple mixer control 'IEC958 Playback AC97-SPSA',0
Capabilities: volume volume-joined
Playback channels: Mono
Capture channels: Mono
Limits: 0 - 3
Mono: 3 [0%]
mythtv@stella ~ $ amixer set 'IEC958 Playback AC97-SPSA' 0
mythtv@stella ~ $ amixer get 'IEC958 Playback AC97-SPSA'
Simple mixer control 'IEC958 Playback AC97-SPSA',0
Capabilities: volume volume-joined
Playback channels: Mono
Capture channels: Mono
Limits: 0 - 3
Mono: 0 [0%]

I don't remember monkeying with this value when it stopped working so maybe something changed it for me during an update, or maybe ALSA's behaviour has changed. Thanks for all your comments  |
