Hi, |
2 |
Message is to Randy and others that have been helping me with my |
3 |
audio problems with xine. This evening I discovered the root cause of |
4 |
the problem of no sound when playing DVDs in xine. Unfortunately I |
5 |
don't have a good solution yet. Maybe someone knows how to fix this at |
6 |
the command line? |
7 |
|
8 |
OK, xine does produce sound, but this machine has multiple sound |
9 |
cards and it's choosing the one that goes to the home theater system, |
10 |
not the PC's sound card: |
11 |
|
12 |
mark@dragonfly ~ $ cat /proc/asound/cards |
13 |
0 [ICH5 ]: ICH4 - Intel ICH5 |
14 |
Intel ICH5 with ALC655 at 0xfa081000, irq 21 |
15 |
1 [default ]: USB-Audio - USB Audio CODEC |
16 |
Burr-Brown from TI USB Audio CODEC |
17 |
at usb-0000:00:1d.1-1, full s |

When I thought of this possibility I turned on the HT receiver, |
21 |
switched to the correct input and low and behold DVD audio was |
22 |
playing. Didn't test to see if it's 5.1. The HT receiver is hooked to |
23 |
the USB device which seems to be marked as 'default'. However hardware |
24 |
setup hasn't changed and earlier versions of xine went to the internal |
25 |
card so something has changed. |
26 |
|
27 |
I don't see anything in /etc/modules.d/alsa that defines the second |
28 |
card as default. Does anyone know how Alsa does that? |
29 |
|
30 |
It's possible that Alsa getting too cleaver by half and somehow |
31 |
'deciding' that the USB interface is more suited to doing 5.1 than the |
32 |
internal card. If it is then shame on it I say. ;-) |
33 |
|
34 |
Two potential solutions come to mind: |
35 |
|
36 |
1) At the xine command line tell it which card to use. I'm looking |
37 |
through the xine --help listing but heck if I see how to do that. |
38 |
|
39 |
2) Somehow tell also to make card 0 default and see if that fixes the problem. |
40 |
|
41 |
Anyway, so the problem is partially solved. I can go the xine-users |
42 |
list and see if anyone there has a quick fix for this. At least it's |
43 |
starting to make some sense. |
44 |
|
45 |
Thanks in advance for any ideas. |

Cheers, |
