This generic computer is ASUS A7N8X-X ver2, AthlonXP 2600, 512 MB ram, 500 GB IDE hdd. I got tired of intermittent sound on a similar motherboard, and decided to replace it with this one. When I got to Wary 5.1.1 full install desktop, I tested onboard sound and got no sound. So I went into BIOS and disabled onboard sound (AC'97 audio controller). Then I installed a sound card in the middle PCI slot. Rebooted. Still no sound, so I tried another card. No sound, so I tried another sound card. No sound, so I installed another sound card. No sound. I even tried another PCI slot. Nada. There is a speaker icon in the systray, for every card, and for onboard sound as well. I have also run ALSA Sound Wizard. Still no sound. Any idea why this is happening?

Hi....

Wow, looks like you've tried quite a few cards but I'm 99.9% sure that Puppy supports the AC'97 chipset so I think something else is going on here. Why don't you take out any PCI cards and let's try getting the onboard to work first? Wink

First, after re-enabling the onboard sound, can you duplicate this problem by using another pair of speakers? How about a pair of headphones plugged into the jack? Also, check the sound properties and make sure the volume is turned up and everything is unmuted.

What does dmesg report concerning the sound, anything? Please post the output...

Code:
dmesg


Here are some other commands that might be useful.

I've also seen a couple posts about changing the chipset or device's number but I'm not sure that's your problem. See here and here.

Regards...

Here's a curious thing. I ran ALSA and came up with nVidia nForce2 AC'97 Audio Controller (MCP) (rev. a1). This identifies a large chip on the motherboard, centrally located where one expects to find the South Bridge or even an onboard video chip. The curious thing is, there is also a small chip Realtek ALC650, which is a sound chip. I wonder why ALSA does not see the Realtek chip. Anyway, it's something I could normally work around, but not on this board, because PCI audio cards are not working, which makes no sense. I'm guessing the Realtek audio chip is dead.
Code:
# cat /proc/asound/cards
 0 [pcsp           ]: PC-Speaker - pcsp
                      Internal PC-Speaker at port 0x61
 1 [nForce2        ]: NFORCE - NVidia nForce2
                      NVidia nForce2 with ALC650F at irq 21

nforce2 APU or Realtek ALC650 or both?
http://www.tomshardware.com/forum/45909-28-nforce2-realtek-alc650-both

NFORCE2 Audio Processing Unit / Realtek ALC650...What?
http://hardforum.com/showthread.php?t=717589
Quote:
The NForce 2 audio solution is completely digital, there is no DAC integrated into the south bridge because that would be stupid and increase die size further.

So, if you need an analog output to your speakers (which most do), the board manufacturer must use a DAC to convert said digital signal to an analog signal.

What on a typical motherboard is inexpensive and converts a digital signal into an analog one? Hmmmm. Oh yes!

An AC97 CODEC!
Like the Realtek ALC650.

Unlike traditional mobo designs where the CPU does the digital audio processing however, the NForce2 MCP-T (and -D IIRC) has an integrated DSP that does it itself, thereby removing that (small) load from the CPU.

So, if you need to use analog output with that board, the helpful ALC650 will do the Digital to Analog Conversion duties (and ADC). But that is all it will do.

The problem as I see it: This motherboard processes and produces only digital audio through its nVidia nForce2 APU (Audio Processing Unit). The Realtek ALC650 DAC chip converts the digital to analog before it is output. If the DAC chip is fritzed, the sound cannot be converted to analog for output. Typical PCI sound cards don't produce sound because the signal from the APU is digital. Solution? Is there a digital sound card, or are they all analog?

I'm gonna replace this board with ASUS A7N8X, which is brand new (never used).

Hi...

Let us know how that turns out. Smile

I replaced the motherboard with a similar board. I tested the onboard sound, no joy, even though there are audible system beeps. Don't have high hopes that a PCI card will work, either, but will try. Nope, no sound from a PCI audio card.I'm afraid this board just doesn't play nice with Linux.

Hi...

Again, I don't think the motherboard or the cards are the issue. Take a look again at my first set of suggestions about trying new speakers, etc. Wink

I'm setting up this new system in close proximity to the computer I use every day, and rarely turn off. I simply remove the jack from one computer and insert it into the other. The respective audio ports are not more than 20 inches apart. Fact: the speakers work fine in my main box, and the speakers make no sound when inserted in the new box. I just confirmed the sound failure with earphones--no sound.

I downgraded the CPU to AthlonXP 2400. CPU temperature is just under 50C / 122F. Mobo temp is 33C / 91F.

Could be that the Front Panel connector header needs jumpers to close it to the circuit. (No jumpers = No sound). Its a "10-1 pin FP_AUDIO1" header. Currently, two jumpers connect pins 5 & 6 and 9 & 10.
1 MIC2
2 Aud GND
3 MIC PWR (MIC Bias)
4 +5 VA
5 Line Out_R
6 BLINE_OUT_R
7 NC
8 key (no pin)
9 Line Out_L
10 BLINE_OUT_L

Could BLINE be back line? How do I jumper this header to disable the FP AUDIO?

Quote:
If the front panel interface board is not connected to the front panel audio header, jumpers should be installed across header pin pairs 1-2, 3-4, 5-6, and 9-10.If these jumpers are not installed, the rear panel line out connector will be inoperative and microphone input pins 1 and 3 will be left floating, which could lead to elevated back panel microphone noise and cross talk.

http://www.formfactors.org/developer%5Cspecs%5CA2928604.pdf

It would seem the jumpers across pin pairs 5-6 and 9-10 were correct.

How do I force ALSA to install the Realtek AC'97 driver?

Quote:
1. Make sure that the volume is not muted, the speaker is working, and the device is setup properly under CMOS.

2. Jumper setting, Pg 33 manual. 23) Front Panel Audio connector. There should be two jumpers which connect Line out L to BLINE out L, and Line Out R to BLine out R.

3. If above doesn't work. Unscrew your motherboard from the case and check the location under Front Audio connector. You might find there are two metal supporters (seats?) underneath but there is only one screw hole in the motherboard. The redundant supporter will touch the back of the motherboard, short the circuit and cause the sound problem. Simply remove it and WOW... the sound is back. You should also check the other supporters and see if they are properly protected.

That very well could be the problem. I'm not sure how else to help here. Sad

I tried an Audigy2 card (digital audio?), which produced a lotta noise but no intelligible audio. The forum thread from Hardware Analysis, linked above, suggests that the front panel audio header is shorted on the bottom side of the board, which could explain why PCI sound cards don't work. That thread is full of good ideas. The motherboard's audio design is not standard, and I think ALSA may get confused. This board really does run smooth and fast, but there is no sound. As far as audio is concerned, this board doesn't play nice with any operating system.

I could not get sound working on a new 2 core PC (October 2012) despite much searching of this forum so I bought one of these cheap USB sound cards from ebay and have had sound with no problems. This may not be the most elegant solution but it works with Puppy 412.

Hi Stuart
Thanks
found this interesting also from Patriot about the same card.
