ALSA subsystem looks good. Please, test directly the ALSA driver with the setup for RHEL 7.3 (alsamixer - capture flag in 'Capture' column, increased 'Line Boost', 'Capture' 100% - unmuted). arecord -D plughw:0,0 -f cd -d 15 -vvv a.wav Note that there is no more 'Input Source' in recent Linux kernels for this hardware. The codec is capable to mix inputs together (Line,Mic etc.). The user should select the input source(s) with the "capture' flag in alsamixer. Hi Jaroslav, "arecord -D plughw:0,0 -f cd -d 15 -vvv a.wav" resolves the issue. OK, so it looks like a pulseaudio configuration issue.. |
Created attachment 1204834 [details] alsa-info.sh --no-upload from Fedora 15, RHEL 7.0 and RHEL 7.3 Description of problem: When the customer is working with RHEL 7.0 the command "alsamixer" (ver. 1.0.27.2) cannot change the condition, when the sound. from INPUT connector can be hearing from the speakers through OUTPUT connector. Obviously, the loopback between audio input and output is enabled. When we attempt to make the audio file and play it, "aplay" has not issued a sound. Version-Release number of selected component (if applicable): How reproducible: not reproducible Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Customer is using Realtek analog chip ALC262. There is an improvement in RHEL7.3. Below is the statement made by customer:- "We downloaded the RHEL-7.3 Beta version alsamixer ver.1.1.1 has some improvement, the “Mix” loopback with alsamixer ver.1.1.1 can be disabled. That means when audio input is coming from the external PC it will not be routed/looped to the speakers directly as appears in the alsamixer rev 1.0.27.2 (RHEL 7.0) " Note:- Customer is able to achieve above things in fedora 15 without any issue.
