| Summary | 0000900: Modules for sound card rt5645 missing in kernel 4.20(.7-1.el7.elrepo.x86_64) for CentOS 7 | ||||
| Description | I am using CPU SoC/Intel x5-8350 with CentOS 7. Sound card chtrt5645 (as shown by Ubuntu) is not working. With distro kernel (3.10.0-957.5.1) at least snd-soc modules for rt5645 are loaded (like in Ubuntu), though sound is not working. But in ElRepo kernel 4.20 the snd-soc modules for rt5645 are not even present (in /lib/modules). Can you fix this? I would expect the ElRepo kernel to fix the distro's problem, as it does for Wifi (Broadcom 4345/6, brcmfmac). | ||||

Acknowledging your RFE. It would be helpful to see the relevant vendor:product ID pairing for the relevant audio subsystem, as shown in the output from an lspci -nn command, please. (Either from CentOS or Ubuntu, whichever is more convenient for you.) |

Sorry, lspci does not list any audio device, neither on CentOS nor on Ubuntu. This is the output by Ubuntu: 00:00.0 Host bridge [0600]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series SoC Transaction Register [8086:2280] (rev 36) 00:02.0 VGA compatible controller [0300]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series PCI Configuration Registers [8086:22b0] (rev 36) 00:14.0 USB controller [0c03]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series USB xHCI Controller [8086:22b5] (rev 36) 00:1a.0 Encryption controller [1080]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series Trusted Execution Engine [8086:2298] (rev 36) 00:1c.0 PCI bridge [0604]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series PCI Express Port #1 [8086:22c8] (rev 36) 00:1f.0 ISA bridge [0601]: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series PCU [8086:229c] (rev 36) 01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c) I think cht means Cherry Trail, rt means Realtek. One of the modules in question is snd_soc_sst_cht_bsw_rt5645, which is loaded by Ubuntu and by CentOS distro. I think bsw means Braswell. Hdmi audio works on CentOS, on distro (3.10) and on ElRepo (4.20). |

Thank you for that useful information. There is a kernel-ml-5.0.0-0.rc7.el7.elrepo package that was built earlier today. It was configured so as to make a number of ASOC and codec modules available. That release candidate can be directly downloaded from -- https://elrepo.org/people/ajb/devel/kernel-ml/el7/x86_64/RPMS/kernel-ml-5.0.0-0.rc7.el7.elrepo.x86_64.rpm When convenient, please download a copy, install the package, boot the kernel and then test to see if it resolves your problem. |

Thank you. The new kernel detects the sound card, and the sound card is listed by aplay, hence it is usable. But some hardware parameters are not correctly set. When I play a sound file, aplay reports (sorry, in German): Wiedergabe: WAVE '/usr/share/sounds/alsa/Front_Left.wav' : Signed 16 bit Little Endian, Rate: 48000 Hz, mono [ 697.631399] Audio Port: ASoC: no backend DAIs enabled for Audio Port aplay: set_params:1403: Fehler beim Setzen der Hardware-Parameter: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 48000 PERIOD_TIME: 125000 PERIOD_SIZE: 6000 PERIOD_BYTES: 12000 PERIODS: 4 BUFFER_TIME: 500000 BUFFER_SIZE: 24000 BUFFER_BYTES: 48000 TICK_TIME: 0 |

Sorry, my interpretation (parameters not correctly set) may be wrong. The translation of the error message would be: Error while setting the hardware parameters. |
|
|
This is as far as we, ELRepo Project, can help with respect to the kernel configuration. Closing the ticket as 'resolved'. |

A brief note to mention that the recently released kernel-lt-4.4.175-1.el7.elrepo.x86_64 [1] and kernel-ml-4.20.11-1.el7.elrepo.x86_64 [2] package sets now contain the equivalent configuration adjustments.

I reopen just to say thank you. I made a fresh install with the prelimnary kernel 5.0 on top, and now it works. I do not understand the alsa error I reported, and why it disappeared. Looking forward to check the new kernel-ml. Thanks again. |

Now closing as "resolved/fixed". |
