I use speaker-test for testing the speakers under linux. I have to add that they're working fine in Windows (tested each speaker using nvMixer). I have two independent sockets for LFE/Center and Rear channels (they're not shared with Mic and Line in as in some other products e.g. Epox 8RDA+). I've noticed that the surround51 pcm defined in /usr/share/alsa/NFORCE.conf does some routing on the stream - namely swaps LFE/Center with rear channels and that seems right, because hw:0,0 tested by speaker-test plays them incorrectly. So when doing my test, creating own pcms and else I had it on my mind. However what this bug report is all about is that I can't get any sound playing from the first channel through anything connected to the socket originally (according to the MoBo manual) used for LFE/Center neither using the surround51 nor hw:0,0 pcm. I also tried to make my own pcm but the diagnosis is the same. Here are the facts: My speakers connected just the way they work in Windows. $speaker-test -c6 -Dsurround51 Playback device is surround51 Stream parameters are 48000Hz, S16_LE, 6 channels Sine wave rate is 440.0000Hz Rate set to 48000Hz (requested 48000Hz) Buffer size range from 3 to 5461 Period size range from 3 to 5461 Periods = 4 Buffer time size 2525 To choose buffer_size = 5460 To choose period_size = 1365 was set period_size = 1365 was set buffer_size = 5460 0 - Front Left # I hear the beep correctly from correct speaker 4 - Center # I hear the beep correctly from correct speaker 1 - Front Right # I hear the beep correctly from correct speaker 3 - Rear Right # No sound ;((( 2 - Rear Left # I hear the beep correctly from correct speaker 5 - LFE # I hear the beep correctly from correct speaker (yes it's quiet, but I''m sure it comes from the Subwoofer only) When I create my own pcm that reroutes the 3rd channel to some other - it plays from the position where routed, but nothing ever gets played from that muted channel when routed there - hence my diagnosis. When I use hw:0,0 the situation's the same except the LFE/Center and Rear sockets are swapped, as stated before. Moreover if I turn the switches "Mic as Center" and "Line-in as surround" "on" to use it the Epox way, and plug my jacks where stated, the case is similar but even worse, since it won't play ANY of the first channels (i.e. Rear Right and LFE from surround51 pcm) at both sockets. Second channels (Center and Rear Left) work just fine. Or maybe it has something to do with settings for capture, because I haven't used it and played with it at all? Let me know if they can affect it and if so, I think there should be some notice somewhere (on the module's istalation manual), because I couldn't find any. Additionally when tried to play with the "Swap surround slot" option there was a thought of another may-be-issue that came to me. Namely when i turn the option "on" and physically do the swap, the "Duplicate Front" option duplicates front channels still to the Unswapped plug i.e. I hear the channels through the Center/LFE channels. I think that the "Duplicate front" switch should be affected by the "Swap surround" switch. Don't You think so? I'm in a dead end right now and quite desperate. I also am interested in making Linux work on more hardware! ====================================================================== ---------------------------------------------------------------------- slammer - 02-25-05 12:44 ---------------------------------------------------------------------- I checked it on my friend's machine (same hardware) and it seems the same, so I guess it's reproducible. ---------------------------------------------------------------------- slammer - 02-28-05 21:51 ---------------------------------------------------------------------- Opps... My friend switched from Slackware to Suse and the problem's gone. He can hear all the channels. Hmmm :/ Does anyone have the idea where to investigate on this?
