Hi All,
I just installed CentOS 7 on my Dell Inspiron 7737 notebook/laptop. My sound icon in the task bar shows my volume is at 100%. I have also tried testing the sound through Phonon->Audio Hardware Setup -> left and right speaker to no avail. I have built in Audio BTW through RealTek. I don't know the exact model number. Any and all help is much appreciated.
Not sure I can help here since I've never worked with CentOS, however, for those who might, please go to this page and follow the instructions given there. Then post the results (or a link to the results) in your next reply. This will, hopefully, tell us more about your card and what's going on.
It would help to know the audio chipset. You should be able to determine this by running the command lspci (list pci devices) in a terminal (you may have to do this as root).
I'm afraid it doesn't, apart from showing something's not quite right. It's possible that it's a compatibility issue, although it was my impression the script was compatible across distributions.
Let's try this, please open a terminal and post the results of these commands in their entirety...
Thank you for posting the requested information. My initial guess is that perhaps ALSA has configured the wrong device (HDMI, in this case) as the default. Please take a look at the following threads below to help determine and, if need be, correct this...
[root@localhost Documents]# lshw | grep -A11 multimedia
bash: lshw: command not found
The alsamixer output should be attached
Is this my problem?
Nope. Take a close look at the alamixer output. It says "MM" at the bottom....for "Muted". Un-mute the device.

Wrong. There are TWO devices listed, and HDMI is only one, and it's configured as the SECOND device in this case. The alsamixer output was clear saying it's muted.
Please pay attention, and don't post misleading/potentially damaging and time wasting information.

Let's not start this again, please. While I admit I didn't see or know what the "MM" stood for, my information was nothing of the kind. How do you know the analog device is the default? I've never seen an alsamixer readout give only Pulseaudio as the device name before. I've seen cases before where devices were given the wrong default status, for whatever reason. You will also notice I said this was my "guess," it's something worth checking out, even if it's not the case.
Regards...

Reason: Correction/Added comments.
do you have pavucontrol installed as I think I seen you say you are using PulseAudio. if not install it and open it then click the mute to unmute that just might be all it is.
audio in all of the Linux I've tried is defult mute, I install volumeicon to use my volume setting and to unmute by clicking on that little speaker in the app area on the apts bar.

Yes, let's not start again...if you don't know, then DO NOT ANSWER. Your 'guess' could very likely have rendered the OP's system broken far beyond what they were able to fix. If you wanted to help, then why didn't you look up alsamixer, so you could at least have an idea of what the OP posted, before going on?
Again, your bad advice would have cost the OP lots of wasted time and effort. Pay attention to what's posted, and if you can't give productive advice, then don't answer just to get your posting signature out there, since it appears that's the only reason you post.

Hi...
If that were the case, I wouldn't have spent near the time that I have on this forum.
STAY FOCUSED on the OP's question; if you can't answer it, don't remove it from zero-reply with fluff answers like "I don't know but run this command", or give advice that will cost the OP time/money.

@TB0ne, Your continued posts of this nature are off-topic, petty, and to be frank a bit disappointing. If you'd like to continue participating at LQ please either start using the Ignore List functionality (which I have suggested previously) or learn to not make these kind of posts. As always I am happy to discuss off-line, but the consistency of these have become detrimental and just are not in-line with the ethos we aim for. As a reminder LQ aims to be a friendly and welcoming environment where members of all experience levels should feel comfortable participating. I should note that the technical knowledge you continually show and the time your contribute to LQ is genuinely appreciated and has benefited many, but the expectations you have are sometimes a bit unreasonable (not just in this thread but elsewhere) and the response when those expectations are not met are brash. Being direct is fine, but as I've noted in the past using the Report functionality is far more beneficial and productive for both yourself and LQ in many of these situations.
@ardvark71, I'd agree that solutions should only be suggested if you have a good handle on the issue and have a reasonable expectation that the fix will address the issue. That said, your request for more information was reasonable and it should be noted that the response in this case directly led to the issue being correctly diagnosed.

Understand Jeremy, and my apologies to YOU alone. The expectations I have of others are nothing that I don't have for (and demand) of myself. I work hard, I try to find solutions on my own and use those experiences to gain knowledge and share it freely with others. I don't waste others time with nonsense, and don't lie. Those are the ONLY things I expect from anyone.
I have NEVER, EVER been 'brash' with anyone who has shown genuine effort and followed the simple rules of your forum. And I will also be the first to admit that I DO get terse with those who ask for handouts and do NOT follow the rules.
