Alsa wont detect a USB based soundcard unless there's a non-USB soundcard. Note a lot of PCI soundcards now are actually USB soundcards in disguise.

Please don't put "urgent" in your question or title. It is highly frowned upon (don't take this the wrong way, but it isn't urgent to anyone here, and people here generally don't care if it is urgent for you, and it will make people less likely to help you). See https://meta.stackexchange.com/q/6506 and https://meta.stackexchange.com/q/2950. If it was allowed, people would just mark every single question as urgent, and then it would be worthless

Thanks. /usr/bin/alsamixer returns cannot open mixer: No such file or directory. I'm not able to hear anything. Audio devices are not detected.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
