I believe you can do the required<br> change in /usr/share/alsa/cards/USB-Audi<wbr>o.conf quite easily. The "USB-<br> Audio.pcm.iec958_device" section seems to contain rules for setting the<br> correct iec958 device number for specific sound cards (the correct<br> number is 2 in your case). I'm not sure where to get the right match<br> string for your card, though. I would guess that it's visible in<br> /proc/asound/cards. For example, I have this entry for my usb sound<br> card:<br> <br> 1 [C10 ]: USB-Audio - CA DacMagicXS 1.0<br> CA CA DacMagicXS 1.0 at usb-0000:00:1a.0-1, full speed<br> <br> I would guess that "CA DacMagicXS 1.0" would be the correct match<br> string for this card.<br> <br> If you manage to edit USB-Audio.conf so that you don't need the<br> modification in PulseAudio, then either send a patch to alsa, or tell<br> what change you did and I'll send the patch for you.<span class="HOEnZb"><font color="#888888"><span class="m_-5400913178125605238HOEnZb"><font color="#888888"><br> <span class="m_-5400913178125605238m_4547916924769104144HOEnZb"><font color="#888888"><br> --<br> Tanu<br> <br> <a href="https://liberapay.com/tanuk" rel="noreferrer" target="_blank">https://liberapay.com/tanuk</a><br> <a href="https://www.patreon.com/tanuk" rel="noreferrer" target="_blank">https://www.patreon.com/tanuk</a><br> ______________________________<wbr>_________________<br> pulseaudio-discuss mailing list<br> <a href="mailto:pulseaudio-discuss@lists.freedesktop.org" target="_blank">pulseaudio-discuss@lists.freed<wbr>esktop.org</a><br> <a href="https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" rel="noreferrer" target="_blank">https://lists.freedesktop.org/<wbr>mailman/listinfo/pulseaudio-di<wbr>scuss</a><br> </font></span></font></span></font></span></blockquote></div><span class="HOEnZb"><font color="#888888"><br></font></span></div> </blockquote></div><br></div> </blockquote></div><br></div>
